I have a pretty nice STTNG, but the finish on the coin door, a few bolts here and there, and the gun shooter need to be repainted to make it even better. I started with the gun shooter. The gun is easy to remove and disassemble, but you will need a security torx bit to get the thing apart.
A simple sanding to smooth it out and a coat of Krylon Fushion black is perfect for a base coat. An automotive clear was a applied for 3 coats that makes it extremely durable and also give it that “wet” look. It has a real smooth touch to it. I also painted the heads of each mounting bolt and all the rust was removed from the trigger. I think it looks better than new!
