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 HVLP gun.....8 PSI at 50 CMF turbine compressor...nice warm dry air. Unfortunately it is a pressurized cup and the cup gets in the way. Neither of the guns I got for my paint job work as well...gravity feed. Both are low pressure guns that don't atomize worth shit.
I shot the last few bits with the HVLP gun and it was much better and ya don't have to worry about shittage from your compressor.....live & learn. I could not find a better gun to go with the turbine compressor. |
