Ian:
Just as a side note, howdo you use the box fan when you spray paint? (Intake or exhaust)
I use the fans for intake when painting in the garage (with the doors open as well.) Also for exhaust after I'm done or after I move painted signals/parts inside, to get the Ace-equipment enamel smell out of the garage.
The only fans I use for exhaust
while painting are fuse-intact fans, or normal window fans.
However I no longer paint inside, after this happened.Ian A.
