Spraying technique:

Large file (almost 4 meg), but it's kind of cool to watch. Nice to see the nasty old get covered up!

Sweeeeeet. (dodge hemi commercials)

I'm still amazed at how little overspray is produced with HVLP systems. It's a whole new world.

I hate those damn Dodge hemi ads except for the one where the idiot rides in the truck and daydreams about being "best friends." I actually hate that one too except for the fact that he's pulling the cigarette boat with Sweeeeeet writen in script down the side. Hehe. Get a chuckle at that every time.

What kind of HVLP equipment did you use? What economical equipment would you recommend?

It's a "Showtime 90" self-contained turbine HVLP system from [url=tthp://www.tptools.com]TP Tools[/url]. These are also on Ebay all the time--brand new, but "scratched". That's where I bought mine; I think I paid $100 less than a new one.

If you're already set up with compressed air, I'd recommend that you buy an HVLP conversion gun for use with your existing system; these guns are readily available in a wide variety of price range and quality.

The advantage of the turbine system like mine is that it is completely self-contained and can be used anywhere with 110V. I like the system itself well enough, but using it highlighted a few issues, which may or may not be specific to the marine LPU paint that I used in conjunction with the gun.

Orange peel can be a problem, since the turbine slightly heats the air that it sends to the gun. This can cause the reducer to flash off too quickly, as it is evaporated by the heat as the material is sprayed. This can lead to improper self-leveling on the surface. To get around this problem, there is a several-pronged approach.

First, a longer air hose helps the air cool over its longer run. I used 50'.

Second, running part of the hose through cool water can help remove the heat from the hose.

Third, it is best to use a slower-speed reducer than you normally might choose for spraying with traditional equipment. Also, the amount of reducer required may much higher than the manufacturer's recommended amounts.

For these reasons, I recommend using a compressor-based spray system, unless that is something you don't ever see acquiring. The turbine system is good, and the problems above can be overcome. Just beware of their existence and plan to practice with the equipment and the paint to find the way to the best finish possible.

I was pleased with my unit from TP Tools, and don't blame the problems on the Showtime unit itself. I have gotten good results with it, though it did take some adjustment of technique and the way the paint is mixed and prepared.

BTW, definitely go for a gravity-feed gun, regardless of the system you choose. It's well worth it.

I'll second that. I use compressed air and a DeVilbis JGA for years. Switched to an HVLP gravity feed gun last year and love it.

I still envy your lack of overspray, Tim!
