I used the Crystal Guard Quick spray on our black vette and I think dust must have gotten on the car before it cured, because now there are small bumps all over the car, except on the back where it's vertical. This was the second coat,and it didn't happen after the 1st. I haven't touched it since then because we were out of town, but I have to do something soon to fix it. A rep. suggested that I use a clay bar to smooth out the
surface. Has anyone ever used one, and how exactly does it work?
We do have the Zaino products, and I think after I figure out how to clean up the car with out scratching it, I'm going to use that on it. Black is so touchy!
I've put 4 coats of the CGQ on my white Xfire and it looks great and doesn't have any problems. That's the wierd thing, because they are sitting right next to each other in the garage and I put the last coat on the Xfire right after I finished the Vette.

Hope someone can be of some help.
Thanks,
