I finished all the bodywork on my 72 skylark and was going to spray it with evercoat slicksand. I bought an ultrapro napa hvlp gun and a 2mm tip to go with it. I've mixed it up twice and its done the same thing both times. It spray blotchy and doesn't atomize properly, it sprays on like a spray in bed liner. I am using a craftmen compressor set at 90psi with a gauge on the gun at 40 psi. I tried more pressure, less pressure, messed with the pattern and cannot get it to spray properly. I have contacted the evercoat rep and said he has never heard of the product doing this. I tried reducing it with acetone and helped but didn't solve it. I completely dissassmbled my gun and found nothing wrong! Would air hose size or a water filter have anything to do with it cause i'm outta ideas and quite frustrated!ha haou: Thanks!
What is the temp outside the warmer the harder it is to spray don't use a strainer in the gun make sure the vent on top of the gun is open.
Try using 15-20 psi, set on the regulator not the cheater valve on the gun. I repped evercoat for a short time, all I can say is....follow the directions. The product is awsome and the only way to go.
So just ditch the gun gauge altogether? Its about 23'C outside when i tried spraying. I found the the more pressure i gave it the better it seemed to spray. Keep in mind that these hvlp guns are internally regulated to spray 10-13 psi, at least thats what the instructions for my gun said and have read that before
Have you ever hear of google? ha ha Its a high build polyester primer that only uses a hardener to cure.
Basically a sprayable Bondo. Polyester based. Even smells like Bondo! I've used it on small parts that have rust pitting....spray it on, sand it smooth. Fantastic stuff!:TU: My gun has a small tip (1.3 mm), so it needs help to spray the thick paints.... I like to crank up the air pressure ....50 psi at the regulator. HVLP guns might specify a low pressure at the air cap, but it takes a lot more air pressure at the inlet of the guy to meet that spec, so don't get misled.
I've used (and will always use in the future) Evercoat's Featherfill. This stuff is amazing! Fills 80 grit scratches easily, and sands like a dream. I'm usually not one to use a lot of filler, so this is a good alternative to having to fill the car with gallons of "mud" over and over to get it right.
