You're laying it on too thick per coat. You should do several thin coats. Each coat should barely cover it until it's a uniform color. If you have time, you should sand with 400-600 grit wetordry between coats. I did 5 coats on my Filco cover in flat white. Finish with a couple clear coats (gloss or satin your preference). Then let it sit for a week. DO NOT TOUCH IT. The result will be fantastic if you are patient and let it cure. As with most things like this, painting requires some skill, but not much. It may take some practice to perfect how you hold the can, distance, stroke length (sounds dirty, huh?). At any rate good luck. Metalliqaz put out a great article on how to paint. I followed his article for the most part, and it turned out decent (not perfect).
