Spray Guns - HVLP

[Chris Larson]

Hey Van-
I sell Capspray HVLP http://www.spraytechinc.com/products.html  to paint
stores and refinishing shops in Northern California and Nevada.
The benefit's of HVLP -
- Better transfer efficiency, i.e. how much paint "sticks" to a given
substrate.  Conventional air spray is rated by the EPA and AQMD at 25-35%
transfer efficient.  HVLP is rated at 86.9% transfer efficient.  The benefit
to you is a "wetter edge", less dry overspray on areas you've already
covered, and theoretically, less sanding, less masking.
- Better control.  With most decent HVLP systems out there, you can darn
near airbrush with them, BUT NOT QUITE.  One of the demo's I do is to paint
my thumbnail ( silly, yes, but it shows painting contractors how you cut in
with it ) then go out to a 8-10 inch pattern, without touching the gun
adjustments at all.
- There are two types of HVLP systems- Compressed air conversions, and
turbine systems.  Compressed air is generally cheaper if you already own a
decent size compressor, but you may have water issues unless you are
meticulous with your moisture trap.  Turbine systems are great for our type
of use, but more expensive.  They provide a clean, dry, constant source of
air.
- Be cause of the above, you generally get a better finish.

All that being said, my gun alone generally sells for $350 or so in the
paint stores, and a good turbine system is a little over $1000.  If you are
using it every day, I highly recommend people spend the bucks.  However, for
our hobby some of the cheaper compressed air conversion guns will do just
fine.  I have used and tested some of the cheaper turbine systems out there,
i.e. Campbell or Wagner, and they are OK, but the gun is not as good in
terms of adjustments and durability as a cheaper compressed air gun.  They
are generally plastic, while the compressed air conversion HVLP guns are
metal, with both fluid, air, as well as trigger adjustments, and are
rebuildable.
I hope this gives you a general overview of HVLP, and will help you in your
decision.

All,

I've been reading this thread with great interest regarding the HVLP guns. I
was taught to spray with the standard spray gun some years ago, and that is
all I have ever used. I get nice results.

I have always wanted to try the HVLP guns, but just never have. Anyone use
both, and have a preference, and why.

Also, Amir, you wrote:

I've used a DeVilbiss touch-up gun and it's nice, shoots Concept paint at
around 20 psi and the automotive primers at around 40 psi...It's clean and
work perfectly.....Yours for $60 shipped with the 8 oz cup.

Where can I find this gun for $60.00 ? I'd like to give it a try.

Thanks,
