Oh, you spray it on then let it gas off a little before hitting with another light coat. As instructed. A few minutes AT LEAST, maybe 7-10 minutes between coats, it takes a few coats generally...
What compressor are you using? What PSI?
About any compressor will work for an air brush, and it takes just a little more for the small Iwata gun. Dry clean air.. Fairly low pressures, like 15-30 and it looks wet, not too much air where it's dry instantly, or is powdery looking...
Have fun....
