Ok, I tried out my new HVLP gun. I was spraying high fill primer. The output was similar to what you get from an airless sprayer for house paint. It literally looks like an orange.
Here are a few things that could be contributing factors: 1. Never used a HVLP gun before 2. 3 year old primer that says "use within 6 months" 3. Cheap Harbor Freight spray gun (no instructions besides an exploded diagram) The primer had settled out and needed serious stirring. I did get it mixed, but it seemed thick. It said thinning wasn't necessary, but after I thinned it a little it worked better, but it still wasn't "flowing out". I didn't want to overdo it and get runs. This is the gun I have HF HVLP I did like how I could spray outdoors in the wind without mega-overspray problems. |

I have an old Harbor freight gun similar to the one in your link. The material knob on the gun has to be turned way down on mine to get it to spray well. Also, primer has a lot of solids and has to be reduced more than regular paint.
