When I painted my 68 I went with SPI epoxy, 2k, high build then sealed it with reduced SPI epoxy. Over that I shot Sherwin Williams dimension lemans blue 5 coats then white stripes. Cleared with 3 coats SPI universal clear. Then wetsanded 1k-3k and buffed it. Still need to wax but I am pretty happy with it. It's not perfect but I am happy with it.
