OK, this is not the most intelligent thing to ask but here goes. I like aluminum spinners for functional reasons. But they would look a lot nicer in some applications if they were painted to match the plane. Every time I've tried to paint aluminum the paint falls off after a bit. Tried sanding and cleaning before painting. An electric starter could not be used. Anybody painting with success? If so what is your technique? I have the VQ LA-7 in need of a red spinner.
