Jeep products (and other manufacturers) of the 80's had some pretty bad paint problems. So bad, that the manufacturers implemented after-the-fact undisclosed warranty coverage on peeling, fading paint and clearcoat. As I understand it, the warranties extended only to the original owner and only for a certain period of time. My '88 Comanche is no longer covered (I'm not the orignial owner anyway), but considering the cost of a new paint job I suggest you investigate whether your '92 Cherokee is covered under one of these so-called secret warranties.
