If I under stand correctly an HVLP is a spray gun of sorts, is this correct? Also 
Is there a good water-borne coating I could use on Premium Luster. I really 
had using the solvent based stuff.

Thanks

Steve

Hi Steve,
HVLP is a type of spray gun. It stands for High Volume Low Pressure.
They spray out a lot of fluid on lower air pressure then the conventional type of guns. Its supposed to
cut down the amount of wasted overspray and also the best type for use with water based paints.
The only reason I know this is my girlfriend uses one in her business for spray tanning. Her's cost about
$800.00 for the gun and special HVLP air compressor.

I’m going to try the little Preval sprayer with some beta water-borne
coating the is being shipped to me.  I'll let people know what I think of
it.  

I would never do enough of the spraying to justify an expensive HVLP
sprayer.  That is really for house or furniture painters and service bureaus
that do a lot of volume.

One problem with water-borne sprays has been their propensity to clog the
nozzles.  I've suggested to the company the is sending the beta that they
find a solvent that would be appropriate to clean the nozzles and sprayers.

There are lots of water-borne coatings, but I'm not sure any have Wilhelm or
other tests that convince me the products are good for the long haul.  Many
coatings yellow, crack, or otherwise deteriorate.  As I've noted before,
there are reasons I switched to the solvent based versions.

Paul,

I've been following your coating experiences.  Thanks for sharing your
findings.  I'm curious if you have direct experience w/any of the
ClearStar (ClearJet - solvent or ClearShield - water) or DCP Systems
coatings.

Thanks,

I've had no direct experience with those products.  ClearStar is near the
top of my list of coatings I'd like to learn about.  Livick has done some
fade testing with coatings, and, I believe, ClearStar did well.  However,
this might just be a measure of much UV blocking agent was put into the mix.
Sometimes this material yellows.  

We really need "good accelerated aging" tests (although that may be an
oxymoron) for these materials.  Better yet, actual long term experience
would be nice.  I can tell if there is going to be quick light yellowing,
but the long term testing is not so easy, quick or cheap.  At least Wilhelm
is taking a shot at it.
