best way to spray on the future is to use the lowest setting on your airbrush and just spray it on...it is pretty forgiving stuff, you just have to find that fine line between too heavy, and orange peel...it spreads itself out pretty well, and as long as you dont over do it, it comes out ok...(if you want to remove it, best thing to do is dip it in rubbing alcohol - works like a champ, and lets you try try again) Good luck
