I'm not a painting expert but I have tried an HVLP gun during a local BOCES
automotive painting course and have also borrowed one from work to paint a 1
meter radio controlled model sailboat for my brother. I felt the results
were very nice and there is a definite reduction in overspray compared with
the standard spray guns I have used. The paint delivery is somewhat slower
than a conventional high pressure gun so if speed is your thing you may not
be happy. Also it was necessary to change to a larger orifice to spray
heavier primer fillers because of the lower air pressure available to push
the material. My instructor said that someone already accustomed to a high
pressure gun would need time to relearn their technique for HVLP.
Charlie didn't mention whether he is looking at a conversion HVLP gun
(converts high pressure from a standard air compressor using a pressure
regulator at the gun) or a turbine based HVLP system which uses something
like a vacuum cleaner motor to supply a high volume of low pressure air
through a garden hose sized feed. The later I have no experience with but I
have heard they add addition challenges because the turbine heats the air
which causes the paint to dry more quickly which requires a slower paint
reducer to compensate. However , I guess its also hard to make runs and sags
with one. I too would like feedback here because I will be commiting to one
type or the other in the near future.
