I used Benjamin Moore M22 (or the zero VOC) equivalent using the roll and tip method on my Aluminum boat. The paint dries extremely hard, leveled well and had great shine. I used rustoleum top sides for the red accents same method similar results.
I'm headed up in mid sept to meet up with an army buddy whose at JBER. Going to try my hand at some fishing and a caribou! Best of luck and post up your results and experience!
