Andy, despite what everyone says about your current process, you are the guru with the 200,000 plus followers. We are behind your techniques and procedures. You are living the life I want. I have watched most all of your videos and have enjoyed watching your process change over time when new tools and products are discovered. The addition of your daughter’s voice is the best. I have a 17 year old daughter. It makes me remember her voice. Keep up the good work. I hope your shoulders are doing well.

There integrity to post something like this speaks volumes about your authenticity. Everyone has screwed up, but you will help many many more by sharing your experience. That's good stuff. I am attempting to do the same thing with the boat I am building. Good, bad, and ugly.

Thanks for the content, Andy! I was trolling forums looking to repair my boat and stumbled on your channel a couple of years ago. You saved me many hours of agony, wasted time, and money. Thanks for teaching the basics and giving simpletons like me the confidence to perform quality DIY repairs.

Love your content Andy. Would love to hear more about how the shop is coming along.

I helped a good friend repair his cap rail on his 32 foot sedan. We used TB 2:1 with f/g cloth and fillers. I wanted epoxy for it strength and tooling properties. We scrubed with water each build up to achieve the shape. Once complete we use TB Total Protect and were very successful. We put 2 coats of TB Total Protect and waited 7 days for full cure time. It was summer and we had 85 to 90 plus temperatures. It appears dry same day but not patience is critical to marry the polyester gel coat over epoxy. We coated with 3 light coats of Total Boat Gelcoat about 2ml thick. We wet sanded and compounded and had very good results. As a general rule any epoxy takes about 7 days to post cure, Patience is key.

Great commentary and it's definitely accurate. My first project was a large hardtop bimini and I intermixed these materials. Gelcoat cured over epoxy laminating resin just fine, but not over any fairing compound. Epoxy barrier coat (nice $$ addition) and gelcoat it worked fine! Different formulas different results for sure.

Thank You. What an effektive way to demonstrate how a tie coat works :)

Thanks Andy this was very helpful!

Doh! Glad for your weekly video regardless 😊

Very diplomatic opening regarding the forums. My feelings, a little knowledge is dangerous. That's why I always refer people to your videos ....the ones you do right!!!

Andy, do you think letting the fairing compound cure longer (as in several days to a week) before gel coating would have made a difference? Similarly, perhaps waiting at least 48 hours before gel coat application over the Total Protect would work better.

Yet ANOTHER great video. You simply know a lot and convey that information in a clear and practical way. I am guessing that you forgot the activator ?

Great demo Andy, and everyone can mess up, were only human 👌 Assuming a lack of catalyst in the second gel coat over the tie coat.

Right on! Keeping it Real.

Uh... is there any MEKP in that gel coat? Love seeing the fail somewhere other than in my garage. 😁

You know how gratifying this is for the rest of us, right? Thanks for the vid.

I’m goin with you forgot the mekp in the second batch!🤪

Andy, thank you for all the great videos. I have a bit of an off topic question concerning paint. You have noted in several videos that topcoat paint is for above the water line and that bottom coat paints are for below the water line. What if I do not want an anti fouling bottom? I would like the bottom paint to look just like the top coat paint. I looked on Alexseal website and I cannot find any paint especially for under the water line. What paint should I use? Thank you.

I’m going to suggest that you did not let the epoxy tie coat completely cure. I have finished off repairs with gelcoat over epoxy plenty of times and never had an issue BUT it’s essential that the epoxy has totally, completely and thoroughly cured, ideally I’ll wait 2-3 days before sanding to get a key for the gel to get a mechanical bond.

Some you need a heavier grit paper too. I've seen primer go onto amine free epoxy and act like it's been spread on a wet or silicone surface as I'd only used 400 grit Mirlon pads. It was a 2 pack epoxy primer and refused to stick properly on west systems till id used 240 or heavier. Went on like a dream and flowed out perfectly to anything sanded with 120-190grit.. put it on anything lighter than that it stone wall refused to work.

Hope you find out exactly what is wrong with your shoulder. And then start the healing process. As frustrating as it can be. Do not try to rush rehab. I know that is easy for folks to say. Keeping a positive attitude was very difficult for impatient me. But it got me to buy my first boat with an engine. But that has led to the slippery slope of a "bigger" boat...... with the transom that I should rebuild.

I did this exact mistake. Large repair of super structure using epoxy. Faired using total fair. Gel coated over the top. Would not even set! Lots of research and three coats of epoxy primer later I was able to gel coat. For my latest repair I painted!

Would using Total Boat Polyester Fairing compound work better? That is what I purchased because I am use to working with Poly CSM and 1708.

Hi Andy This happened to me when i was fixing my boat, i used the same fairing compound you used there, then I applied the gelcoat , three days later the gelcoat was like the first day :( , i had to remove it again , and before i apply the gelcoat once again i use a 2 part primer by Total boat,by the way i left you an email at your online store page, I’m interested in buying some Alexseal paint , Thank you for yours videos

Glad you enjoyed it :-)

I was first think you used gel without wax or PVA and that's why it didn't set, but the contained says with wax. I am guessing the 2nd batch was missing hardener, but also could be really old as well.

Wouldn't it be possible to put a layer of vinylester fairing over epoxy and have a solid chemical bond for gelcoat? Thanks appreciate all the content!

So in the end what happened? I’m confused

I forgot the hardener when i put on my first coat of gel coat. I read you have to remove it and stuff. Do you know of a easier way to remove it. I got most of it off but it was applied over chop strand so theres still gelcoat in all the little nooks and crannies. Its been about a week sense i put on the gel coat so i dont know if that makes it harder to remove. Ive been wiping it down with acetone and that gets a little but not the gelcoat in the nooks and crannies. Is there someway to remove it. Would a pressure washer work? Would it be ok if theres still some left, could i gelcoat over this or do i need to completely remove all of it? Please help 😨.

Total protect needs to be fully cured before sanding. Tech sheet says very important.

Yeah but thats so you don't streak and pull the non fully cured paint about. We know how to get around that mate with light sanding and wet sanding. Automotive 1k primer tells you to wait 2 weeks before sanding mate but you can sand it an hour later if you have heat and proper wet sanding paper like the mirka or Kingspor stuff.

What should I use on a 1985 RV class C that has fiberglass shell on it. Not Aluminum like most RV's. Can see the fibers in it. Should I just roll on some Epoxy paint?? Wipe it with Acetone first ?? Not looking to spend a lot of money and just want it to look a little better

Given the age of the shell a good sanding and cleaning would be my first step. After that is talk to your local paint supplier. I'd probably go with a spray on epoxy based paint used for fiberglass automobile and motorcycle bodies. Rolling seems like it's going to take a lot of extra sanding and multiple coats. The paints I mentioned are mainly for spray guns as they're on the expensive side. That said a lot of guys roll and tip there boat coatings so I guess it's an option.

lol, opinionated people in online forums...?! yup. kinda helpful...? yup. often more passionate than logical...? yup. that's why I come to channels like this, and Tales from a Shipwright, and SailLife, I'm sure there are others. Even with a fail I know you've got thousands of hours of practical experience and you really care about quality in your work, I'm watching for the next video on how to overcome this fail! thanks for sharing

I made all these same mistakes earlier this year with repairs to my boat deck. I used epoxy and Total fair, then applied gelcoat. At first I thought I forgot to catalyze the gelcoat so I cleaned the surface then applied gelcoat, making sure to catalyze. It still didn't cure again so now I did the research and discovered my mistake. I cleaned the surface again and applied a barrier coat before gelcoating again. It cured this time but I'm not happy with the final product. Looks like I will be re-gelcoating the deck again next spring.

The barrier coat was sanded?

No hardener.

I like it ,,

What happened… I did my transom like this.. came out great!

I love that you experiment to find answers and not just following the thinking of “well it’s only done this way” or “ well it’s always been done that way so it should only been done that way. Thanks

Persistence is a great thing

Skipped the induction time for the barrier coat?

Another idea: did you mix Gelcoat and Topcoat? Same stuff, one with wax one without...?

Did that gel coat have wax in it?

i dont know where the screw up was but maybe you got confused with the cans and used the gelcoat instead of the tie coat. easy to miss, because maybe it is also white. about the gelcoat application over the fairing compound: i wasnt expecting it to not cure since the fairing had at least one day to cure and was hard enough to be sanded. i was expecting secondary bonding issues being that polyester over epoxy is generally a "no-no" but the reverse is actually better than polyester over polyester.

Proper epoxy will bond to anything better than anything. I've repaired a glass fuel level dial on an old Aladin Blue Flame heater with west systems and its lasted 10yr in horrible hot then cold conditions. When I say hot I mean 200+ deg and its still fine after a decade and people say epoxy stick to anything but glass, no it sticks to glass too I guarantee you it does.

Oh boy, a cliffhanger!!! ;-)

I'm surprised you left us hanging without finishing the project. Your catalyst is crap or your not mixing it right. I always skim coat with dynaglass between epoxy and polyester fillers. FYI

Ha That's how I do it. LOL It just proves even the prows can mess up sometimes.

It would be nice to see you actually working on a boat

He's got over 200 videos... most of those are of him working on boats and demonstrating boat related products/repairs. I'm sure you can find something...

Ohh ohh Andy forgot the catalyst🤣 BTW I have water based epoxy paint here in the UK and it actually takes 3-6days to skin dry, that's the norm for it and the longer it takes apparently the better the bond is. Also we don't get epoxy "fanboys" here in UK forums Andy, it's usually people arguing that poly or Vinyl is as good as epoxy on things like transoms that will cause a pointless argument as factually the proper epoxy like west systems utterly spanks poly and vinyl on transoms its not even close the difference, the shrinkage on large transoms for a start can need a second repair less than 3 weeks after laying it and if you don't get the transom strength back that's lost to modern marine ply being nowhere near as well laminated as the old stuff then your big heavy motor will hanging an inch or two away from where it should be unless you bulk up on the layers, then it becomes a guessing game. Proper epoxy you don't have that issue so it's not really up for dispute, epoxy is the clear winner mate no iffs or buts so I'm suprised anyone even argues about it.

Well, it just be's that way sometimes. Some days you're the windshield, some days you're the bug! And we all make mistakes. Especially when rushed, even when we are the ones rushing ourselves.

i guess you did,nt use a rough enough grit on the sanding disc probably 180 ,instead of 40 or 80 grit i,ve had this problem getting gel coat to harden on fresh 10 day epoxy lay up hard to use an epoxy primer on it with a rough grit finish,normally tie coat is used to seal old antifoul if its decent smoothness saves removing old seal with tie cost barrier or if a single pack paint has been used put tiecoat on and then it lets you use a two part paint or poly gel coat

Did you forget the hardener?

I dont know either as all the UK forums I'm on nobody argues about it they know epoxy is superior but not always needed or the easiest to work with. Most guys I know who are strictly epoxy admit they do it as an extra safety barrier and if the customer wants the extra expense, which in the UK most people want proper epoxy fixes they specifically ask for it. I'd say there was more guys on the forums denying epoxy is the superior product because they personally used some brand of poly or vinyl that did the job. It's only later they come on asking why their transom repair cracked within 3weeks because of shrinkage do all the epoxy guys come on and say "we told you so" I mean I use all 3 types of epoxy on different areas but I'm not silly, I'm not going to argue that proper epoxy isn't the best. It clearly is so I don't get the "fanboy" bit he's talking about. They are factually correct so?

Lol... That's not the ending I expected.

Where it went wrong: turning up to work today? Oh well, educational anyway😊

Did you use the wrong catalyst?

Forgot catalyst Andy?

forgot to put the catalyst in the gel didn't you😊😊

Like everything in life. There is a right; way a wrong; way a way to make money.

The epoxy drinking game………And now I’m drunk inside of 7 minutes

Andy....you forgot the tie coat !!!!!!!

I am new to this. I have never done any fiberglass work. My hopes are to learn how to do it and do it correctly. I can appreciate an honest mistake. I pay attention to details very well. Some call me anal retentive but that is ok.Makes me better at whatever i set my mind to. So this is my guess of what went wrong. I saw that you mixed your tie coat up but I didn't see it applied. Did you forget to apply it first? i saw the two cups at the bottom of the waste barrel. I am guessing you sanded the base epoxy coat to prep the surface but then maybe forgot to apply intermediate coat before applying gel coat. Just my humble guess. Second theory, Do you mix the gel coat with the tie coat for a chemical reaction to get it to bond?

You forgot the catalyst I've done that

At 4:49 I assume you are applying gray paint but you don’t really say what you are putting on at that point. Then later you are putting a tie coat over gray paint. Frankly at that point I figured the fumes were having their way with you.

oks product --- hard to save left over poly/ another reaSON TO USE EPOXY

"epoxy" 1 shot "it is what it is" finish your beer.

Looked like he put the gelcoat on the fairing compound without adding the "tie coat" lol... he basically just repeated step one of the experiment again.

Dude, what I like about you is that you screwed it and kept in the video. Just a reminder of what not to do. Did you used Mekp or fogot that? I watched older video of gelcoat used over epoxy and it can be done; however, for the guys that don’t want to go with polyester, vinylester can be used and is more water-resistant than poly. Thanks for your contents🙌🏻👍🏻🙏🏻

Bit confused.... 😅

Forgot catalyst ?

When I read total waste of time on the thumbnail I erroneously thought it meant that doing a tie coat in general was a total waste of time, not watching the video 😌

The fiberglass god made a mistake?! What??!!

You painted wrong side?

Forgot the wax….

No catalyst,

Wrong gel coat ?

Brain farts,it happens when the mind has to much shit to think about.And when the brain farts,it takes some of our knowledge out.🤭🤭

Something tells me you forgot to catalyze the gel coat. Oops.

That pooch is no longer innocent

Oops.

Lol

I'd say you accidentally spread on your wife's biscuit dough

??????????????????? It was an epoxy based barrier coat?

Bad batch of Total Boat?

Am I the only one who does not understand this video? You can't put gelcoat on top of epoxy. Unless you put epoxy tie coat on first, then gelcoat. But when you did that it didn't work. I am missing something here but I have no clue what.
