I have a turbine type HVLP setup and a Sharpe Platinum HVLP gun that
runs off of an ordinary compressed air supply. In my experience you
_can_ use the turbine gun for both epoxy primer and hardened acrylic
top coats, _but_ one characteristic of the turbine is that when it
compresses the air, the air temperature goes up and you are going to
be spraying with 90 to 110 degree air. Result for me: orange peel
galore on the top coat (even with slow reducers) -- which took a lot
to rub out with 1000 and 2000 grit paper and polish. The Platinum gun
I bought several years ago is a model that was made for the hobbiest
in that it does not need 12 cu ft/min of air supply to function. The
flip side of that is that it is slower than a pro would want to have
to make money painting every day. But it does produce a very nice
result. It is not cheap. DeVilbiss and others make good HVLP guns
as well. I stopped reading the fine print on their offerings so I
don't know how much air they need to do a good job.
HVLP uses (wastes) less paint so at the price good paint comes for
these days it makes sense to use a HVLP gun even if you don't care
about environmental issues.
