I use, (when I'm ambitious enough to strip a model) the brush-on kind of paint stripper. If Darrick knows of a good spray-on brand, I'd go with that because the brush-on stuff has to be apllied 2, sometimes 3 times to remove all vestiges of paint. If your wanting to remove paint from plastic, I've heard of all kinds people using Oven cleaner in a spray can, such as Easy-Off, but I have not tried this myself. If your going to try this on plastic, test it on an expendable piece first in a small area to see if and/or how it's going to affect the plastic. . . :confused
