Hello all, this is my first post on spi. I am a young hobbyist painter but I have a few paint jobs under my belt. I recently bought the devilbiss starting line 2 gun kit (identical guns with 1.8 and 1.3 tips) and I've been having a lot of trouble with orange peel. Devilbiss says these guns require 13cfm@ 30psi, and my compressor is rated 13.4cfm@ 40psi. The paint doesn't seem to be atomizing enough and yes I've tried fine tuning ALL of the gun settings, as well as air plumbing, paint reduction, etc. My compressor is plumbed with 1/2" pipe up to a 25f 3/8" hose with high flow fittings, so I don't think I have an air delivery problem (that was my initial suspicion). I have tried pressures anywhere from 20-50psi at the gun. I get marginally better results when I crank the pressure up but that also causes a hellacious fog of overspray which I don't THINK is necessary. I am looking for any guidance a more experienced painter could offer. Could I be too close to the air volume threshold for this gun with my compressor? maybe a defect in the gun itself? With my inexperience, I might be making a stupid mistake with my gun setup but I have never had this much trouble setting up a spray gun before. I know I will get more expensive guns recommended to me, which I would love to have someday, but being a college student I would rather not throwdown $500 on a gun right now. I'm just trying to finish this jeep I'm painting with Matrix SS. Any tips or advice is much appreciated, and sorry for the long winded post!
