I've often heard that using a bathroom exhaust fan to exhaust finishing odors
is bad idea, but I'm sure there are certain conditions that would have to be
present for it to really be a danger.
Consider this room:
9' x 12' x 7'
South West corner: A door that opens to the main part of the basement
North West corner: A door that opens to the great outdoors (screened)
Consider this idea:
Mount a 140 CFM bathroom exhaust fan in the North East corner (opposite
the 2 doors). If my calculations are right, that's about 40% more than
the minimum CFM for a bathroom of that size.

Planned uses: Occasionally exhaust odors from primer, paint, mineral spirits,
oil based stains, oil based poly, farting, etc. No spraying. Brush or wipe-on
only. Small projects or small parts of large projects. e.g. stain a headboard,
paint a dresser, etc. Not to be used when the air is dusty, although
adding a holder for a furnace filter is a possibility.
What would it take for this to go boom?
FWIW, the fan shown below, placed on a stool by the door to the great
outdoors hasn't blown the place up yet. Of course, it's only been about 35
years, so there's still time.

That thing is a beast. I don't know the CFM rating, but it'll dry a pair
of jeans in about an hour.

Does it run on DC? It looks like it should. May be an old Vortex unit.

War story: I lived and worked in Sweden for a year, around 1974. I was doing
a lot of soldering, and the rosin smoke was giving me headaches, so I asked
my business partner for a low-speed fan to blow the smaoke away. He went down
to the sub-basement of the large condo block he lived in, and came up with
this beautiful old enameled cast iron with brass table fan, which I cleaned
up and re-oiled, and then plugged in. It sat there humming slightly and
moving slowly. Lightbulb! Loked at the nameplate - Gleichstrom! (DC) That fan
had been in the basement since the 1920s, when Sweden converted to
alternating current, because it was too good (and too expensive?) to just
throw away. So I added a silicon rectifier bridge to the fan, and it worked
like new. It will outlast us all.
