OK--I'm a complete moron when it comes to car finishes. Most of my cars, I just keep clean because I buy them new and keep them forever. However, I have a 1998 Ford Contour V6 that I bought for my daughter. It has been a good for the 1.5 years we've owned it, but that V6 does run hot and there is some clear coat 'checking' on the hood. Is there something I can use to prolong the clearcoat to stop it from flaking off or turning white? As of this point, it is not flaking off, just has the cracking lines in it when you look close. I just want to stop it from getting worse. Any help would be appreciated--thanks
