Hi, nice informative video. What resin do you recommend. I am unable to achieve that dry finish on the inside of the laminated part and it sounds like a partially cured part when i knock it with a metal rod on it. Maybe mixing ratios are wrong or i am not using correct materials. And for a fender like this, can i use 2 x 350gsm csm with a plain weave cloth. or can i add woven roving for strength? Not planning to ride with a pillion. Please help. Thank you

I always recommend using an isophthalic resin (iso-resin). Catalyse between 1 and 2% with MEKP catalyst and use at close to room temp. Yes, you can reinforce with woven roving wherever needed. If the inside of the part remains tacky but the part is solid and stiff you can add wax air dry to a little resin and flood coat it. Hope that helps.

Use epoxy laminating resin, this is the best option, it is least toxic, it has longer pot life, it is not jelling, it is stronger than another resins. To make the inner layer dry put paper towel on the inside face, roll on it with molding roller and then peal off the paper towel with excess of the resin.

Thank you, I DO Have a Question : Your largest project, in terms of surface area and in terms of # layers of, type of and weight of the cloth(s) ... How much epoxy resin, in terms of gallons, was necessary? Please detail that for me: 1. Square footage of surface area 2. How many layers were used in one layup (was it glass, Kevlar and/or carbon, was it a combination), 3. the (estimated?) weights per sqf of each layer and most importantly of all: 4. How many gallons were necessary for the layup or better; for the entire project?

I don't use epoxy resin, it's polyester resin. The largest project I've done was 78,000 square ft. This fender project used about 1/2 litre of resin. You can count the layers in both the mold and the part if you watch the whole video.

Hey man! Nice video! I was wondering how can I restore/remake missing side on my lotus Elise. The left front side smashed-missing. I bought this wreck to restore. I am familiar with frp repairs but never done such big job before.

Nice car to work on! You can use spray foam as a base for the section that you need to redo. Step 1)Tape/mask the underlying area so you can remove the foam easily after the work is done. Then foam fill the complete area using 2 part urethane foam. Step 2) sand down the area to 1/4" lower than where you want it. Step 3) trowel on bondo over the entire area and sand/shape it to your liking with 40 grit. Step 4) spray a high build polyester primer Step 5) sand down using 220 grit then wetsand 400 grit then 600grit. Step 6) spray PVA mold release and build up a mold of the area like I did in the video Step 7) make your part in the mold like I did in the video Step 8) remove all the bondo, foam and tape from the car and install your new fiberglass part Step 9) sand the part to 320 grit then paint using automotive paint. Hope that helps.

@@Mofiacdid you have to thin the gelcoat down at all or could you spray it as is? If you did thin it, how much and did you you acetone or styrene?

@Mofiac

3 жыл бұрын

I shake the gelcoat container for 30 seconds and that usually thins it enough. If you purchase spraying gelcoat no thinning is needed, just mixing. Don't overmix or you'll break down the thixotropic nature and it will sag. If it's old gelcoat or you're using a spraygun with a smaller needle and aircap then you can thin it with hi-gloss additive from Hawkeye Industries. If you use acetone to thin you weaken the finished product. It will still cure and give reasonable results as long as you don't thin with more than 10%. Styrene is a recommended thinner but it's nasty stuff so I don't use it and it tends to make it sag easily. Hope that helps!

The grey paint is called a high-build primer. Any type will do such as acrylic-urethane from PPG or Imron, but the one I used was a polyester high-build primer from Evercoat. Hope that helps.

Can i ask why you purposely made a texture finish to mold? I thought the fender ideally should be as smooth as possible to have less work for the usable part.

@Mofiac

2 жыл бұрын

Yes, I can. I did so for 2 reasons. 1) small minor scratches and scuffs don't show on textured products.(class A finishes that are black are notorious for showing scratch marks). 2) By spraying on a texture, I didn't have to wetsand and buff the part to a high gloss. Saved me a bunch of time. Hope that helps!

How to get polished surface finish bro. Even after polishing .pin pores visible Which grade polishing wheels used Plz 🙏 reply

@Mofiac

2 жыл бұрын

If you're polishing gelcoat after demolish and you're noticing pinholes it could be due to your catalyst. I'd need to know the materials you're using, the application procedures(is it sprayed on or brushed on), the catalyst ratio, etc. If you're using crafted wheels to polish, you may be overheating the part. I'd need to know more to help you out. POMF

If you're getting pitting after polishing it's most likely from outgassing during the cure. You are either applying gelcoat too thick; wrong catalyst ratio for that gelcoat(too much catalyst), or using the wrong catalyst for that gelcoat. Check the gelcoat manufacturer's website for recommendations regarding application thickness, catalyst ratio and catalyst type. If done properly, you shouldn't get any pinholes at all. Final note, when polishing, check how hot the part gets in the buffed area. It should only be warm, never hot.

I spent over 480 dollars gathering all material's and I just don't want to have incorrect ratios with the products I have bought. I would greatly appreciate your words of advice as it has been months that I have set my fiberglassing project aside.

What type of resin and hardener do you have. Sounds like it might be epoxy...if it is, the manufacturer's website will have the proper ratios by weight and/or by volume. Not all epoxies are mixed at the same ratios.
