must be a lot easier to not bleed with a air brush. i got special trimmers tape that is supposed to be really good. im just noob and a little heavy on the spray. i did a really light first layer and then used a hair dryer to dry it. i made my mistakes in the second... i should have let it dry a bit more and tehn press down everything. instead i did a heavy layerNice bug T-rav. I paint all my own bodies also, I use electrical tape instead of masking, helps with colors blending. Also I use an air brush instead of the cans. Oh and I like the hail piles in the yard.
