I am rattlecan painting my R20, green and black w/ cream trim, to match the colors of the late '20s Fords. (Love that combo!) What have you guys used as a topcoat? It feels like one will be necessary, unless as time goes by the paint dries a lot harder than it has so far. I have sprayed with Rustoleum High Performance Enamel. This seems to be good quality paint.
At the moment it is drying after the last coat. I will post pics of the painted frame later today or tomorrow.
