About two years ago I painted an F350 with SPI B/C, came out excellent minus the orange peel. Very little trash that I remember. Fast forward to this Mack I am doing and I have trash everywhere. I do a sealer of 1:1:1 then three coats of Nason SS (another topic for another day). The surface texture is excellent out of a SATA 5000, minus the consistent trash that gets everywhere.
I have a stick framed, plastic walled (and taped) booth, with filtered air coming in making positive pressure, just like I did two years ago. I filter the sealer and paint, clean with both cleaners (6+ hour wait time after), tack panels, tack the stands, tack the gun, cup, and line to the floor. Today I sprayed in a dirty shirt and shorts, and ended up with the same result I did when in a tacked off suit. The filter is a CT30 which is brand new, along with a brand new flexzilla hose, new bulb filter, and clean gun. This trash appears both during spraying panels and also if I just shoot a concentrated spot on a scrap panel outside the booth, and most of it occurs when spraying color (NOT SEALER). It looks like very fine sanding grit but is too small to really judge without a microscope.
I have sprayed just air into a clean towel and get no visible contaminates. Besides throwing in a coalescing filter or tracking down much finer strainers, I am about at wits end because, there is just too much of it, unless I am like PigPen from the Peanuts. Thoughts?
