I went back and looked at the picture and I don't think its dust. you couldn't get that much if you painted out in the desert in a wind storm. I think you could have a problem with your clear or activator or somewhere, I think your probably spraying It on.? it'll be interesting to see what others have to say.

I did the spraying in a tent closed all the openings with plastic painters drop cloth.
The temperature was around 75 degrees Fahrenheit
I forgot to use a tac cloth but I cleaned the primed bumper really good dawn soap water. I've been hit it with prep all wax and grease remover , and rubbing alcohol last.
600 grit was my prep for the base
My base coat is matrix mpb . What I did with this was I was afraid to get runs so I set up my gun by spraying a piece of cardboard where the fan pattern was about 6 inches,oval and even coat on the pattern. holding the gun still for about 2 seconds with no runs is where my setup was It was around 30 PSI
My gun is sprayit 30000.

So what I did with the base coat is I was scared to get runs so I did about four coats with 15 minutes flash time exactly in between. The first two coats light last 2 a bit heavier. I got a tiny run on the second coat and since it was light I was able to send it out with 2000 grit after my final base coat before I cleared.
I waited at least a few hours before I started to clear maybe 2 hours or so
Now when I went on with the clear coat as I was setting up my gun I got about a 8-in pattern but again I was afraid to get runs so I think when I set up the gun and I held in the trigger for a few seconds there wasn't much clear on the surface but I left it that way so I wouldn't get any runs I figured I'd do a few more coats to make up for it. So I hit it with two light coats and two medium coats. It wasn't till the last coat that I noticed all this crap all over
as far as my compressor setup I don't have any filtration The only thing I have is one of those orange balls you put before the regulator on the gun itself I think it's for water. I also took out the filter in the gun because I heard it clogs and I always filter the paint before I put it in the gun. It was a 1.3 tip on the clear coat I think 1.5 for the base
