jonnyboost, laquer is a single stage paint, that does not require a clear coat. but there is a clear coat for laquer. bc/cc must be clear coated, it is alot more durable than a single stage paint, it will not fad, because it had a uv light inhibiter in it. It also is alot more chemicle resistant. you might be able to buff the hazyness out like everyone else is saying. If the hand polish dont work try a finsh cut/leveling compound on a buffer, it is alot more agressive. if that dont work you could try a turbo cut/buffing compound which is alot more aggresive. if that dont work then repaint is the next step.
Lhorn, you probably dont have to stip the good paint, but a paint jnob is only as good as the prep work. i would strip the whole car so you have a good substraight to start with, the new primers, sealers, and base/clear products are alot better than what what was used 17 years ago.
