I've even used Rust-O-Leum to paint with. It can be sprayed by thinning it 30% with either their thinner or mineral spirits. Main thing is don't be in a hurry to apply it all at once. I usually shoot on a tack coat first. This coat doesn't completely cover the panel, you can still see some of the primer showing through. I usually let it "flash" (dry) for about 15-20 minutes. This allows it to become tacky for the next coat. Then I shoot a 2nd and usually a third coat of color on allowing the same 15-20 minutes between coats. As Woody said you have to apply your coat 'wet" so each pass will flow into the next.... John
