After roughing up the surface, we just used a brush and put a good coat on it, I couldn't tell you the thickness. Then we had a little cardboard tube with a hole in the end. You pump it and it would put out a fine powder. You shouldn't need to press it on. I can see about getting you some pics of ones we have already done if you wanna see how we did all of our decoy heads.
The only thing I would worry about flocking is the heads.
