It doesn't take long on any given gearhead forum for someone to mention that the Harbor Freight HVLP guns are super cheap and do a surprisingly good job considering the price paid. Fair enough, I'm all for saving a buck and as someone with a history of gumming up cheap spray guns I appreciate the fact if the gun gets nasty I could just chuck it as well. That said, with decent automotive paint running $120 for a PINT, it would take very little time indeed to make it cost-effective getting a better gun in order to improve transfer efficiency or elevate my novice technique from sand and recoat to good-enough for a Jeep. With that in mind, what do folks here do when moving up? Is there a rig that will make me a better and more efficient painter that can be had on the cheap? Is it worth buying a top-shelf gun or would I have to be a good painter to actually appreciate the difference? If it matters, I've been playing with DuPont Chroma-base / Nason Full-Base but I'm also making the switch to PPG Concept/Deltron, or at least trying to.
