I switched from convention spraying to turbine powered HVLP several years
ago. Both Harbor Freight and Rockler have <$100.00 units and I believe the
unit you are talking about is going to be similar in that it has a turbine
unit rather then a compressor. A small but not insignificant difference.
In any case I started out by getting a remanufactured Campbell Hausfeldt
unit that ran under $200.00 from the factory. I like the HVLP so I upgraded
to a much more expensive Fuji Q4. A beautiful and quite tool.
My point is that I've used both an inexpensive unit and an expensive one.
I've also followed most of the posts regarding HVLP units in various forums.
So, based on experience with an inexpensive unit, a up town unit, and the
vast majority of the posts I've seen on the subject, any unit that produces
four to five PSI at the nozzle and eighty plus CFM, and apparently even the
inexpensive units do, will give you an "as good as the user is capable of",
finish assuming the proper nozzle/viscosity,.with standard woodworking
stains and finishes. Latex paint may be stretching the point a bit.
What you lose and what may be important to you is ruggedness and longevity.
Taking the compressor alone, they run hot and heat is a killer of any
machine. One has to assume that a very inexpensive unit imported from Asia
is not going to have the quality of parts in it's turbines and long and
continuous use will quickly take it's toll on such things as poor quality
bearings. Going further there is the use of plastic, low grade aluminum, and
non stainless steel parts in the gun. They will require careful attention
and maintenance to keep them in top operating condition. Of course even an
expensive gun should get the same thing but it will give you more wiggle
room if you have a lazy day.
In short, there is a very high possibility that the unit will do the job but
for how long it will is very much up in the air and will depend a great deal
on how it is used and the care it gets.
Deft is my nitrocellulose lacquer of choice, Crytalac my water based lacquer
of choice. With the Deft I go out of my way to get the spray/non brushable
type, however I don't believe the inhibitors in the brushable Deft that is
now so common in the home stores will greatly hinder the spraying process.
At least I hope not since I just know I will be eventually forced into using
it due to it's ready availability over the non brushing type.
