Thanks guys for the replies. I tried the Perfect paint again on some more test pieces and the results were better this time around. Basically I took Rcpilet's recommendation, but not quite as far as the hot tap water. I just brought the paint up from the basement into the house and let it sit for a few days to warm completely to room temp(70 deg.). I also used white primer instead of the gray that I used before. The combination of the 2 changes seems to have worked. The paint sprays much more evenly without spitting and the color matches pretty well for a spray bomb.
