I think you don't have the gun set up right
you have to mix your primer/reducer 50/50 and strain it before going in the feed
your prep work looks pretty bad
clean clean clean everything first
wet the floor down
get you a filter
practice your spray pattern and technic on something flat
there are a ton of videos on you tube that will help you
stopping and starting in the middle of a panel is going to do that if you don't have your set up right and you aren't spraying consistantly
