Do you think that an actual 2k clear would work better? Perhaps even better if it was topped off with Opti-Coat 2.0?

Wow! I would never think you could get great results like that in the driveway. Fantastic job!

I know this is a really old thread, but I'm currently working on a similar project. The car is a low mileage 2001 Pontiac Sunfire. Other than a pretty serious case of delamination, the car is in near perfect condition. The delamination is on the roof and the top rail of the driver side doors. It doesn't make economic sense to get a professional paint job, so if I can make it look okay from 10 feet away, this project will be a success.

After sanding off the bad, I am down to the primer in a few spots. I will use Duplicolor to cover these spots. Should I sand the undamaged spots on the roof and re-clear the whole roof? If so what grit? I was going to sand the undamaged spots with 800 grit sandpaper so the new clear would have a good bond, but after reading the posts from Bradley 5.0 I wonder if that is a bad idea. I thought that if I just sprayed right on top of the old clear that it would not have a good bond. I thought if I sanded the old clear, that the new clear would fill in and cover the marks. Is that wrong?

Please Help! Thanks!
