Endless on my Challenger, which had the clear coat start peeling off it shortly after I bought it ( :mad: flippers!!!) , followed shortly by some of the topcoat, giving it a pretty interesting "sunburned" look. And of course my Duster to Demon conversion, resulting in a redneck two tone. I just say I'm going to drive them 'til all the paint falls off, then it will be all one color. But seriously, to do a full paint job I'd have to stop driving them for a bit, and that sucks, so, I keep driving them. Ugly and functional is fine by me.
