I'm about to spray my upper and lower today. About what psi should I set the regulator for. I figure each airbrush is a little different but a general range would get me there a bit faster. Thanks in advance.
This is not my first time using an airbrush but it's been about 20 years since.
About 20 psi give or take. Spray it on a test piece, adjust PSI until it comes out smooth and even. Make sure the air / coating ratio has it going on wet and not starting to dry before it hits the surface. If it is it will look gritty. Use light even passes until its coated. Dont go too thick. Good luck and post a pic when your done.
Edit: If you have any questions or concerns I will be in until 1630 CST give me a call

Well I finished it. I know it is a bit boring, being colt grey and all, but I was interested in doing something that I couldn't screw up too badly. Now that I have tried my hand at this I think there is some color in my future.
How they started out. Used A1 upper. Roll marks filled with JB Weld on lower
I also disassembled the charging handle, rear sight and full lpk. Toothpicks worked very well in the rollpin holes. Acts as a nice handle to use while painting and it insures the hole isn't filled.
Complete. Sorry about the upside down pic. It's to show the rollmark gone but resolution sucks a bit, hope you get the idea.
It's hard to tell from the pics but the finish is very smooth. I ended up with about 4 or 5 coats on the major parts, less on the small parts with critical clearances. For reference that would only be the magazine catch, rear sight screw and take down pins.
I bought the kit with the preval sprayer but after reading A LOT on here I picked up a airbrush from Harbor Freight. I already have a large compressor for working on cars so I skipped that part. I was spraying indoors (well ventilated) and didn't want to run a mile of hose. I used one of my 10 gallon portable tanks with a regulator/dryer installed on it. With 120 PSI in it it was more than enough to complete this "small" project.
Thanks for the advice Joe and I am looking forward to more "colorful" projects in the future. Heck, my brother-in-law just saw the A1 last night and asked me about painting a couple of guns for him.
Sweet. Looks really great.
Shot it today. Awesome. Thanks guys
Looks great - nice work! Good looking retro AR.
