i know you can paint ar's. what about other rifles? there is an older used .22 rifle at the LGS that i was thinking i might pick it up and paint it just to have as something different. ive heard people say krylon. are you refering to the spray paint? and also would it stick pretty well to a wood stock and blued barrel? what sort of prep work do i need to do? just hand sanding? or is it more intense?
