I have the HF HVLP. The only things I’ve sprayed with it are water (for testing) and Sealcoat/BIN primer, both extremely low viscosity fluids to work with. The end results were very good but I found a lot of reasons why I would not consider the HF HVLP a good long-term solution (I certainly plan on upgrading when the unit breaks).

My main complaint is that the air bleeds into the fluid cup, resulting in finish leaking out of the gun through needle onto the handle. I haven’t tried to troubleshoot how best to tackle the problem.
