Ok, I finally got some good paint and got the desired smoothness to the fiberglass. I had it pretty **** smooth and then primed it and wetsanded with 400 grit. Then I added 3 coats of this paint I had mixed up at an auto paint store, I had to mix it with a certain ratio of hardner and reducer. It cost $70 for a pint and it was thinner than water when I finished mixing it. The difference between using this stuff and spray can paint was night and day.
