Thanks Oliver, Stick and BobbyLee!
BobbyLee, I use Rustoleum Gloss Protective Enamel, And then the Rustoleum Gloss Clear Lacquer spray. When I did the borders, on my Coonass sign, I sprayed the clear lacquer first, to prevent bleeding around the boarders, as it did on the letters. And after I sanded the top again, cleaning the excess from around the border (the next day, after it dried, of course), and went to blow the dust off, I blew off part of my painted boarder. Which is what I was afraid of. The paint didn't stick to the clear lacquer. It didn't bleed, but the paint also didn't stick, where I wanted it to!! So what is a sanding sealer? Is that anything like what Barbara recommended, using a conditioner??
Will a flat black bleed less, maybe?
