You have a very clean shop, one of the better dust free shops I've seen .Very well organized everything has its own place well maintained spray equipment, super hi-tech ventilation system which you exhaust straight into the environment, I'm sure your neighbors are really thankful of that . Do you let the dust get really saturate the air before you begin spraying or do you try to gradually let it build up ? I personally use a ladder which helps me get the correct distance to what I'm spraying . I too try wear the same clothes I sanded in when I'm spraying . Keep up the good work.
