My brush is blowing plain air no paint, thinner, nothing. I sprayed a lifetime white no problems, sprayed good. Cleaned with thinner, then went to a createx flo orange it sprayed good for awhile then it eventually quit spraying. I tried to spray thinner back through it and nothing just air. It seems to do that with me when using the water based paint, and ive got it thinned down with water. I have a badger I believe its a 200 series brush with the adjustment on the back. What is going on with this thing?
