[Shop-talk] Garage ventilation?

I don't see why not ... but why not put the exhaust fan between the attic
and outdoors ?  
My garage 'attic' is open to the garage (I store car parts up there), so
that's what I do.  For the moment, I have the exhaust fan's thermostat set
fairly low, but powered from the light switch for the garage so it only runs
when I'm out there (and the weather is warm).  Ideally (someday), I'd like
to add a second thermostat that would run it any time the attic got over
100F or so, to reduce heat gain to the house through the (mostly
uninsulated) wall between them.

Insulating the west wall (which in my case is mostly the door) made a big
difference too.
