I also use Master series, and I like the silver. Anytime you can brush it on you will get better adhesion, you can spray on a 2nd coat of the same or top coat with just about anything including base coat. ....matter of time how far you want to get into your project, painting over nuts and bolts is not ideal but stripping down to a bare frame takes a while.....
