air brush hickuping

I was priming my large B 36 peacemaker when my pasche air brush kind of burped back thru the paint cup sending primer drops all over my half done primer job . any ideas what causes this . this is the first time i’ ve encountered this it kept up all through the spraying any help would be appreciated thank,s

Stop painting-I know. Tear down your A.B. & clean it. Sounds like a clog somewhere between the cup & nozzle.

And while cleaning your AB repeat over and over :

The air brush is my friend,

The air brush is my friend,

The air brush is my friend …

then youll feel better
