For restoring ABS bodyshells on radio controlled cars, I used to use brake fluid to remove paint. It has to soak a while (24 hours+) but removes most paint finishes without hurting the plastic. I've also had some success with mild oven cleaners over the years too.

When you mentioned acetone, I thought "Oh, no, acetone is used to WELD ABS plastic." I've read online that oven cleaner can be used without damaging the ABS. But great job anyway!

I had a SNES controller I painted back in the 90s. I soaked the shell in soapy water and purple power for over a week and the paint just came right off with a toothbrush. Just have some patience.

If I remember it was called a G-Force card. I had one of my 1200.

Bis auf das Bundeswegr Game, hab ich alle gezockt. Super Arbeit mit dem 1200er. 👍

I think respraying that is probably an better way to get it sellable. Although it wouldn’t be considered “original”. But the wet sand did a lot better than I’d thought it would and it’s a lot better neo for sure. For the future thinner or Benzeen (naphtha) work great on paint removal too.

@16:27 I am surprised to hear that, only because I saw Vipers advertised a lot in UK magazines and they were one of the cards I fantasised about getting for our A1200 (never bought an accelerator in the end, not much use for it with the Amiga market being pretty much dead after 1995). I sometimes saw accelerators advertised as M-Tec but I didn't realise it was the same as the Viper.

I tend to go for a scrubbing brush and warm soapy water first, if that doesn't shift it I move on to methylated spirits and then IPA if meths doesn't work (but check because it melts some plastics and never use it on polycarbonate). That shifts a lot of paints or at least softens them up so they can be scrubbed off with a stiff brush and has the advantage that you can soak things.

WOW that A1200 looked so bad! I was very lucky to get my A1200 almost 5 years ago in GREAT shape! It had just been recapped and came with a working clean tank mouse and an 8GB CF card as an internal hard drive. I had always wanted an Amiga since the mid 80's and when I saw this SWEET looking A1200 I grabbed it for more than I should of! At that time in July 2018 only a few were being listed and they looked worn. Most were A500s so when the only A1200 popped up one day as a new listing I clicked the buy it now of $750. I know I over paid but no A1200s were coming up for awhile and this one was just so nice. 1st thing I bought for it was 8MB fast RAM because WHDload needed the RAM to run all the programs. The next thing I bought was a ACA1233n which gave me an 030 @ 25MHz & 128MB of RAM. A year later I bought the Vampire V1200v2 which was not cheap, and way over kill with an 080 @ 85MHz & 128MB of RAM. I wish I had just stuck with the ACA1233n. TY for all the GREAT content! You are looking well!

I saw a YT video on the Vampire and how it ran all the 060 demos and programs like elite super good and had to have it. The Vampire back then cost me around $500 back then with shipping.

I wonder if the dodgy silver spray job was done after the original colour began to degrade, it would would be hard to imagine anyone looking at a beautiful pristine A1200 and thinking "Hmmm, what these needs is to be covered in cheap paint" :)

Maybe a stiff bristle brush would help you clean the grill?

If I were you, I would test some "gentle" paint removers on the inside of the bottom half to see if they melt the plastic. Also cellulose based paint thinners might have worked too. I wouldn't take a sanding paper to it for sure since it would remove the texture as you soon discovered. Nice find though, it is best to put it in the new casing you mentioned.

It's quite interesting, that you can buy recap kits for the 1200, where the electrolytics were replaced with ceramics. It's a controversal topic, but I think it's always better to replace with the "original" electrolytic caps. I bought a 1200 last year, which was recapped. But it's a wild mixture of SMD electrolytics and ceramics, "recrap"! 🤨 Although the machine (with TF1260) works fine, I think I'll do a right recap one day!

We had that discussion here too. I stand to my choice. The argument that Commodore engineers choose these for a reason is ok, but I think the reason was to reduce noise on RF (I don't care about) - that was a big deal back in the day since many used a TV set ... and price. The others were just cheaper and Commodore and ESCOM especially was very price sensitive.

Please correct me, if I am wrong: I did some extensive (maybe not extensive enough) research into this and this is what I came up with: 1. Ceramics (the one I used) have a lower tolerance. This should not be a problem in the context I use them, since the engineers did a good job. 2. Ceramics introduce noise. This might be true for RF/Compostie, but the RGB I use looks fine. If there was a problem, I would switch to the electrolitics. 3. Ceramics are brittle ... true, if you bent the board after soldering or if the board would not be mounted into a case. 4. Price - and this seems to be the real reason there are no ceramics in place in the first place. Ceramics are more expensive ... back the day a lot, nowadays a little (if you go for volume that might still hurt, but I am doing a one off here). Please let me know if I missed something. That is all I could come up with!

@@RetroWK The thing is, electrolytics and ceramics have completely different electronic "profiles". If the computer is at all stable with ceramics, I'd say you're very lucky. I've done a few years with electronics in school many years ago, and what I basically ended up with was "if you didn't design the circuit, and don't completely understand how it works, don't replace part a for part b" :) Commodore's engineers had access to both ceramics and electrolytics, and they chose electrolytics for just these ones. I'd say "trust them" and just get the same parts. They are a bit harder to solder though, so you may have to desolder the keyboard-header or the audio-plugs to get the one behind there in place in a proper fashion. I usually go for the keyboard-connector, since those pins are small and easy to desolder with a vacuum-pump. Atleast you didn't use tantalums. When they go bad, they just explode. And leave a nice little crater if surface mounted.. Try turning on an old IBM 5150 and count the seconds before one of them just go pop. Usually with a nice fireworks display. I still replace those with tantalums.. and have a batch at hand when they go out :)

Lol, bloody hell, what a disaster - NEVER put undiluted acetone on ANY plastic unless you are wanting to destroy it for a laugh. You can use acetone to remove paint/stains etc from plastic, but it MUST be diluted - the amount of dilution required varies from plastic to plastic and you are best off testing in a small area INSIDE the case where you will not see it. I have good success with a mix of 20% acetone to 80% methylated spirit.
