I sprayed my engine bay and bottom of my car in SPI Matte black, mixed 4:1, last year. Now, I am on to painting some trim pieces (window drip cap, Windshield trim, etc). I want something glossier than the Matte black. What happens if I reduce the matte black? What about using it at 2:1? (since 4:1 is glossier than 6:1, and 6:1 is glossier than 8:1)
