Well, I got my A/B today! Its an early Christmas haven't got a chance to get my air tank and try to hook it up yet, but hopefully tonight I can get a chance to try it out and practice a little. Thanks for the opinions guys!
I went up to the barn tonight and set up the air tank I plan on using and played with the brush a little. The double action is a little hard to get used to, I pointed it and pushed the button, and nothing but air? I was like "great, haven't even had it a whole day and its broke"! Then I remembered I had to pull the button back, which made a splatter the size of Texas I think I might need to turn down the air pressure just a smidge
