I have seen a Jeep Cherokee and looked pretty good. There was a 70 K5 Blazer on ebay recently that way as well. However, if I was buying I wouldn't touch a vehicle sone that way with a 100 foot pole. Who knows how much rust and damage was covered up when it was done.

Have you ever tried getting spray-on liners off of a car? That is one of the most painfully tedious things I've had to do on my car yet. The rear wheel wells had some kind of spray-on liner, and the only way I've found to get it off is with a heat gun and a scraper. And you basically have to get all of it off that way, because trying to get the big stuff off with heating/scraping, and then going back and getting the small stuff with a wire wheel hasn't worked for me very well. Is there some type of chemical agent that eats liner material?

Also keep in mind that one of the golden rules of buying a project/restored car is to be wary of undercoating on anything. Anytime I see that, especially when it's fresh, my first thought is "what is he trying to hide under there?"
