Those oilless compressors are pretty wimpy and don't produce much CFM. You have to loose that 1/4" hose, that is a big time CFM robber. The 1/2" pipe can be a problem too. You want 3/4" pipe and 3/8" hose as short as possible.
"Test panels" I love hearing that! I can't believe the amount of guys with no painting experiance who will set up a car, mix up $1000 of materials and spray it without ever spraying a test panel! Good for you!
Barry, I know I need to add that information about the hyper resin clears. I didn't this time because I knew we were taking about OMNI. But I need to emphasize READ THE TECH SHEETS for tip needed for the particular product.
