Well, on the 67 Camaro's, I seem to like the original colors of the Camaro's the best. You can get them with clear coat. We used on my 67 RM paint with Rubberseale Clear. I didn't like the stock marina blue, so had a custom mix made. Actually, here is my vote, but it is based on a 67 RS Z28.

Just my opinion..
