Hi, Sorry for the off topic post but there seems to be a large
knowledge base regarding Harbor freight products here. I'm looking to
buy a rig for spray painting. I would like it to be general purpose
for use with different finish products But my initial use will be with
latex house paint. I'd like to try HVLP for the advertised benefits of
less overspray and bounceback. I see HF has ITEM 7902-5VGA HVLP
conversion spray gun with a remote 2qt cup for $99.

I like the remote cup as I could then spray overhead to do the eaves
on the new addition to the house and have to stop and fill the cup
less often. This unit looks suspiciously like the Wagner HVLP
conversion gun I have seen online at Wagner and Gleem Paint.
http://store.yahoo.com/gleempaint/hvcongunw2qr.html Has anyone used
the HF (or Wagner) rig with latex house paint? Did you thin the latex?
By how much? I have no doubt that either will work for lighter
finishes but am looking for further insight as to the thicker latex.
My compressor is a Devilbiss with a 25 gal. tank and claimed 5hp (no I
don't believe that) and claimed to supply 8.8 SCFM @ 40 psi (not sure
about that). Thanks for any info to make an informed purchase.

You'll need to get a different air cap and needle, the one supplied
with the unit is too small for thicker materials like latex, you'll
need one with a bigger hole and the matching needle. The part numbers
for mine were listed in the manual. I've only ever used mine for
shellac and auto paints so I've had no experience with latex. If it
were me, I'd go rent an airless rig for the one-time use on the house
along with a pressure washer. The pro airless rigs usually come with
a multi-gallon supply tank. As far as bounce back, the HF HVLP gun
has a little less mist floating around than a regular spray gun, but
it's still there. Not at all like the turbine-type high-end HVLP rigs
I've seen at the woodworking shows. I've gotten a lot of use out of
mine, was a good deal for the money, but you still have to watch out
for the overspray. My compressor is an oil-less portable with an 11
gal. tank, it keeps up with the stuff I finish, mostly small
woodworking projects. I don't think it would do for house painting,
it's rated 4.4 CFM at 90 PSI.
