HI Moose, if you look at the videos that Adam has done, there are a couple by forum member Jarrod who demonstrates how own booth, which instead of a fan has running water in the back of his booth to catch the overspray! Very self contained, and there is also an exhaust in there if he so needs it, so that can be added later on. Maybe even try a blower fan to PUSH the overspray out of the booth?
