I bought a set of GGD NYC Empire State Express passenger cars and the observation car needed some work with the rear lighting and roof. I created a new rear light for the roof with my 3D printer and then carefully trimmed it to fit. I filled gaps with putty and have primed and sanded it twice. The rear roof is plastic even thought the sides and larger section of the roof are aluminum. The challenge I have is the paint to match the roof.
What strategies have been used to try to color match the paint? Have people used the 'big box' home improvement store paint matching and what paint have you used? What about automotive shops? What type of paint for plastic? Mixing yourself?
