Okay, I sound like an idiot, but I tried to do a video illustrating the spraying process.
1. You have to set your spray gun to spray according to your preference. Do this buy spraying a 2x4, a box, the legs on your work table, or whatever.
2. When you spray, keep your gun square with work piece. Try not to bend and flex your wrist. Keep your wrist straight and move your arm. That way you can keep your spraying consistent.
3. Do not start or stop spraying over the work piece. Start spraying in the air, and move over your work piece. Don't stop till you are spraying air.
4. You want to move fast enough that you are getting a good even wet look, but not so slow as lacquer/sealer is building up, running, or starting too look like your looking into water.
5. Overlap fan spray enough to keep an even coating/appearence.
6. (1) pass is equal to the entire workpiece being evenly covered (1) time. (1) coat is equal to (2-3) passes. When you deal with lacquer products, 3 passes is generally about all you want to apply. Sometimes, you may want to wait 30 seconds or a few minutes between passes to make sure the lacquer isn't building up or getting too wet.
If the lacquer/sealer looks like its hitting the body to dry, move your gun closer. Too wet, move your gun farther away.
