How can I remove sun deteriorated plastic decals from a painted bicycle frame without damaging the paint?
Peeling off is not an option, I have tried scraping off with a plastic scraper to no avail. Have also tried Goo Gone (citrus based solvent) and Oops! (a stronger solvent) with a non scratch scrubbing pad. I was able to peel the decals that werent' cracked from the sun but the others are basically baked on from the Arizona heat. Would a heat gun work? How careful do I have to be not to damage the paint? What about something like 2000 grit wet/dry sandpaper?
