I sprayed the frame using PPG Omni MTK single stage urethane, flattened with 1/3rd PPG One Choice matting agent, and reduced 10%. Sprays very well and covered great since it was going over the black epoxy. Nibbing the Epoxy made the paint lay down much smoother- as you can see in the "wet paint" pics.
Straight out of the gun-
Starting to flatten out.
