First off I want to thank everyone for all their advice and help! I painted the truck today and it didn’t turn out too bad for someone with a $140 Devilbiss paint gun, a dirty garage, no experience spraying clear, and not much experience painting in general. The bodywork turned out real nice. But, it should have after 40 hours! Well, the paint didn’t lay on too bad. But.. what is strange is pretty much only the driver’s side quarter panel had some pretty bad orange peel. I did get a couple of runs as I have a bad habit of slowing the gun down and laying down a heavier coat when it looks as though I’m spraying dry. Now, I’ve only used my HVLP gun like one other time. It just seems so strange to me to have such little air pressure coming out of the gun. I had like 9-10 psi at the gun. I’m used to using a siphone feed conventional. I pretty much had to mix up all the paint as I had 2 separate quarts that I mixed together to make sure I had a uniform color. With that said, does non hardened paint have a pot life? It also seemed like I was spraying dryer than I should have been. Ok, I also have to admit that I never have made any adjustments to the spray pattern since I bought the gun. I did use medium reducer and hardner as that is what I had gotten. It was only like 58 degrees out today. Any advice is always appreciated! Thanks as always! Jack :rock
Where’s the pics??? :blink:
Glad it worked out well for you.
The unhardened paint, that is the unhardened basecoat? You were using Martin Senour solvent, right? Might be a short life if it is reduced as some of their products used the active reducers. Otherwise solvent base can last a very long time in a well sealed container.
Yes Ben it is the unhardened basecoat. And yes I am using the Martin Senour solvent. And yes it is reduced. The guy at the paint store gave me a gallon paint can to mix my paint together, so it’s reduced in a sealed gallon can.
Which reducer did you use with the base?
I’ve never used Martin Senour, but I have used Sherwin Williams (same stuff) in the Ultra 7000 line and a little of the AWX.
I think 9-10 psi at the gun is a little too low :whistle:
Ben, the reducer is NAPA Crossfire CR234. Ding, the tech sheets said to spray 6-8lbs.Thanks, Jack :rock

That means 6-8 psi at the aircap, which you can’t measure unless you have an air cap test gauge. Easiest way around that is see what psi your gun is recommended to spray at and that should get you to 10 psi at the cap, and reduce it from there 4-10 psi and you can get 6-8 at the cap.
With all that said it requires enough air and proper delivery of said air. If you fall short you may have to bump up the psi a few pounds or adjust the gun a bit to compensate. Your best gauge would be a test panel and your eyes, if what your spraying on doesn’t look the way you want, adjust until it is adequate.
Thanks Ryan. I thought 6-8 sounded pretty low. I just adjusted the regulator at the gun to 10psi. What really sucked was the fact that I pretty much had to paint it being that we aren’t probably going to have any more days around 70 up here in Pennsylvania. It was only like 58 when I painted it yesterday. I know what I have to do next time! Get a test panel and adjust my gun, psi, etc. just to see what kind of atomization I can get. You guys are so knowledgeable!! Thanks as always! Jack :rock
