Here's my trick after lots of bad paint jobs and some really good ones.
I spray the primer and sand once with about 320, then another light primer with a 400 sand.
Lay up the colour, if using Hammertone or epoxy I try to spay on a really warm day and put down about 3-4 coats one hour apart, with hammertone the last coat is a bit thick we are close to lunchtime. I let it set in the sun and by then we're about 4 O'clock and the product is still warm, without cleaning the gun I lay down a few thin coats of 2 pack clear, I thin this a bit more than a normal clear so it bonds with the first layers and the clear mixes with the remnants of colour, after 2-3 coats about an hour apart, a nice deep gloss. Cover and leave.
Allow 4-5 days to cure and then a light Wet sand with 800-1200 and a light but full 2 pack clear if you don't have a good gloss.
Usually you'll get a really good gloss from the last 2pk coat but sometimes a touch to address blemishes is needed.
In the end... Bullet proof paint.
Good prep and primer are the essentials though.
