Chip You don't want to sand it for sure. The scratches will show through. Floquil sells a [url="http://www.walthers.com/exec/search?category=&scale=&manu=&item=&keywords=paint+decal+remover&instock=Q&split=30&Submit=Search"]Paint & Decal remover[/url]. You can also try denatured alcohol. It may soften the Acrylic primer. If not, try giving it a long soak in a strong Tri Sodium Sulphate solution (TSP). You can find that at any paint department. It's used for dulling and cleaning walls before painting. Whatever chemical you use, wear gloves and use an old stiff tooth bru***o scrub off the paint. For some reason the paint didn't adhear into the plastic. There might have been mold release or some other kind of contamination. Sometimes soap will not remove silicone. Giving it a scrub with denatured alcohol will remove silicone and finger oil. Yes finger oil. Even though your hands and clean and dry, there is still oil present. Use white cotton gloves or latex WITHOUT the power coating. Plastic gloves may have mold release on them. I have seen this problem come up in auto body shops. We banned silicone liquids at my shop. Now, what kind of plastic is it? I would assume it's styrene. Next time spray the inside of the shell to see if it's going to adhear. If it peals off again, it could be the paint. Maybe too thin or contaminated. Try using Floquil, but very light coats. Floquil is lacquer based and laquer thinner will melt styrene if it is applied too heavy. Just a light coat is all you need.
