I just picked up a turbine powered hvlp sprayer at princess auto ( much like harbor feight ) for a hundred bucks that seems to work really well for clear coats, both acrylic and oil based. Judging by the picture at harbor freight, I believe this is the same unit. A great buy @ $69.00 for those of you in the USA. Just in case you were thinking of going this route. Cheers.
