HVLP
Paint and body are my
last frontier, so to speak. Over the years I have successfully painted several
engine bays, a couple of trunks and one complete car, all with the standard
paint equipment. Then comes along this HVLP (High Volume Low Pressure) stuff.
Its strong selling points are less material used and not such a "fog"
around you as you paint.
I can't be much of a help to you on advise with this one. Since I bought it 3-4 years ago, my only painting experiences with it have been small parts and full coats of primers and fillers. With these materials it has worked flawlessly. You can get the thing to spray like anything from an air brush to a point where the material is practicably pouring out the nozzle.
Although it does have the greatest of flexibility when it comes to spray patterns, it is physically tough to work with. The hose from the turbine to the gun is large and stiff and could be tough to keep off the car as you paint. They sell a short, very flexible extension piece of hose for use near the gun. I have this piece but have not had a chance to put it to the test. The gun is VERY easy to clean and that alone is a major advantage.
I got mine from TIP, the same company as the bead blasting supplies and the pressurized sandblaster.
