I agree with TX. On my 86 Volvo wagon the clear coat peeled off the roof over time. I had it repainted, but didn't need to spend that much money. Later when the clear coat peeled off the horizontal surface of the rear hatch, I sanded it, masked it off, and painted it with a rattle can of clear coat. It looked fabulous. I don't think I could do that good a job on a big area like a roof or hood, but if I had to do it again, I would do the prep work and take it to a bodyman to do the spraying. Try to find someone who will work with you. They may not want to guarantee the job, but it doesn't sound like this is what you are looking for anyway.
