Angier,
Spraying in a garage does not have to be a limiting factor, at least in
terms of cleanliness. When I spray paint in my garage, I erect a fully
enclosed spray booth made of PVC pipe and the super thin plastic drop
cloth.(see attached) Three box fans in series push filtered air in one
end while a single box fan pulls air out the other. I keep a slightly
positive pressure in the booth while spraying.
I am not an expert in paints (I have only sprayed two stage), but I
believe the general consensus is that single stage is easier to repair
while the two stage yields a richer finish.

[An alternative method is to only use the box fans to blow filtered air into the booth and provide enough exhaust filters so the outflow can happen unassisted and allow positive pressure inside the booth.  Typical paint booths keep the fan motors well away from the enclosed booth's atmosphere... you can imagine how explosive all those teeny paint particles could be if they were set off by a spark from a fan motor.  FWIW.   <Marv>   ]
