paint question

I just finished painting my '67 sprite.
Paint is Nason 2 enamel w/ hardener
It look great except for a few gnats and other small bugs in the finish.
What is the best method for getting rid of bugs and sags and restoring the "just
sprayed" shine?

I'm thinking I should bock the areas w/ 1000 or 1500 grit paper and lots of
water then polishing compound and wax
What is the right polishing compound?
