Purchase a bunch of extra "Fluid Tip Seals". These are little round plastic rings that go behind the Fluid Tip. They do degrade eventually. I bought some at AutoBodyDepot.com. They are cheap. Get lots. 2. The gun is very sensitive to proper cleaning and especially to a proper seal behind the the Fluid Tip. Screw that sucker on tight and reference #1 above about getting extra seals. I replaced it 3 or 4 times already just to make sure that seal is correct. I actually learned this because, as the gun came in the box, there was no seal at all back there. I always got poor paint atomization, of course, until I discovered that. 3. Its also sensitive to a good seal on the metal 'Air Cap', so screw that on pretty tight as well. 4. After EVERY use, clean it out with Acetone or stronger, including taking the Fluid Needle all the way out. It doesn't take that long, and it is essential for keeping that thing working well. 5. Use the small (1.4 mm) Fluid tip. It seems to atomize better with the thin paints that I used. (Vari-Prime and Imron) 6. I used 25-30ish psi at the gun, measured with the trigger pulled. 7. Watch out for moisture in your air system. I used a Harbor Freight in-line air desiccant at the gun to get the last bit of moisture out. 8. The gun works well with or without the plastic liners work great, but I think I prefer using the liners. That makes them all-aspect, and its easier to clean up. 8. As an emphasis, when I had poor results, it was almost always due to a dirty gun, worn-out fluid tip seal, or just not having the parts screwed in enough to get an air-tight seal. Now that I've learned (the hard way) how to use it, I'm very happy with the gun. Happy painting, Jordan Grant RV-6 Slow Build About to move to Goldsboro, NC. Any builders out there??
