Paint Stripping Resin

[LennyB]

Does anyone have any experience stripping paint off a resin body. I've stripped styrene many times using the old standbys but never resin. Don't want to destroy the body in the process. Have an old Modelhaus 1968 Torino HT I painted years ago and then stuck it in a box. Any help is appreciated.

A lot of it depends on what type of paint you're trying to strip away. I primarily use Tamiya lacquers and I've successfully used 91% isopropyl alcohol to strip the paint from resin, just as if it were a styrene kit. The only difference is that with resin, I pay attention to how long I leave the resin soaking and minimize the time as much as possible.

i have stripped resin (enamel ) with Easy Off Oven Cleaner yellow can with no problem. just spray on leave 6-8 hrs use old tooth brush to scrub off old paint. re pete if needed. acrylic paint use 91% isopropyl alcohol.

Thanks for the input. I'm pretty sure it's Testors enamel, but the 80's were a long time ago.

Just wanted to followup. I was able to strip the body with a soak in brake fluid will no ill effects. Odd thing about it though is the paint didn't dissolve as it normally would on styrene. It got brittle and I was able to peel it off. Not sure if this is a chemical reaction of the paint and resin or simply the fact that you can't get good old brake fluid anymore. It's all synthetic and doesn't work as well as the old stuff.

Looks good. 
Was there primer under the paint? I had car painted with Tamiya lacquer over Tamiya white primer. The paint went down bad so I tossed it in the brake fluid overnight. The paint dissolved (probably because it was so fresh) but the primer remained intact. Curiously, the primer had turned brittle, as you describe, and chipped off easily in hard flakes. I sharpened a coffee stirrer and easily scraped it off clean, chips flying everywhere.

Great tips, does it matter what kind of resin it's made from? Why I'm asking is some of these castings have softer resin, I've personally used lacquer thinner with no issues, also nail polish remover, but I'm unsure if it would ruin the resin company's are now using. The stuff I stripped in the past was an R&R kit and a Modelhaus kit. No issues with that stuff at all.
