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. |

This is my 3rd gun like this, they work actually very well when they are new. This gun is only for primer, when I go to shoot the color coat, I will either use a Sharpe or a Devillbis gun. I have used these for color coats but as a rule, they are only good the first time you use them. Once the gun is cleaned they never work as good. So I will use this one for primer as it has a 1.8 mm tip which is perfect for high solid primers. When I do the color coat, I will use a 1.3 or 1.4 mm tip which is best for the actual paint which is thinner.
