I just use two part urethane paint I had on hand from the RV-10 paint. Just like the cowling, I want the fiberglass sealed up and finished with a durable glossy urethane paint that will not absorb any fine oil mist and can be easily cleaned off with either a solvent or non flammable cleaner such as Super Clean degreaser.
