Is there a special trick to spraying laquer primer? I bought the hot rod black primer , you know the flat black stuff, well ive sprayed it 3 times and each time it comes out looking like i rattle canned it, very uneven coats. Whats the secret? Ive cleaned the gun, ive tried different settings, ive tried thick to thin, i do not know why it will not spray even, the gun worked great on all the urathane primer and color i sprayed. HELP PLEASE!
