Clear coat....

Ink,
I have had good success with both Matte Clear and Matte Black from SPI. I used the Matte Clear on my Rocky Mountain Dash insert. The Matte Black is a single stage that you can mix it anywhere from 4:1 up to 8:1. I used 4:1 on all my trim and bumpers, it's more of a satin or eggshell finish than a dead flat black. I did spray outs of 6:1 and 8:1 as well but liked the 4:1 so that's what I used. The 6:1 was what I would call a hot rod black and the 8:1 wouldn't even reflect a flashlight shined right at it
