I went out looking a while ago, and while I found simple green, I've heard that it can melt plastic if you're not careful. So I went looking for something similar to Pinesol; in a small hardware/supply store I found a product called "Jasol Surface Stripper", it's an acrylate floor polish remover (like Pinesol). I've tried it on a couple of things, and it does work well, within reason. it will strip any paint that is over the top of primer really quickly; interestingly it works quicker with black undercoat, whereas a white undercoat comes of really easily, and it will strip the primer too if you leave it for a few hours and don't mind a little scrubbing. You can get an interesting highlighting going if you don't scrub the black undercoat too much.
it might be worth looking for since it doesn't harm plastic, and doesn't smell at all (no gas masks needed)
