What you have is good. When you paint with acrylics, you have to have a semi-wet brush. I have a container of water that I dip my brush in just before I dip in the paint. That thins it out a lil. Don't overwet it or it will drip, and you really don't want that. At the same time, you don't wanna go too thick either. That's how you get the "CLEAN" look, like those '72 DOLPHINS dallcow posted a while ago. White is white and black is black. Don't slop it on and it will look "CLEAN."

Personally, I use Delta Ceramcoat, FolkArt and AppleBarrel. So you're doing good with your paint selection.
