Forgot one of your questions - regarding sizing of a fan.
You should plan for a minimum 12 air changes per hour in your booth, or at
least one complete air change every 5 minutes. Fans are usually rated in
cam (which is reduced by backpressure exerted by filters and other
resistances). I would use a fan that would provide 150% or so of the
required airflow to meet the recommended change frequency.

Doug:
Thanks for that information. At present I am favoring using a
waterborne urethane from Stewart Aircraft Finishing systems. It is
much less dangerous in all respects. They claim that after the paint
cures, it is the same as any other urethane. I'm going to talk to them
at the Copperstate Fly-in this weekend.
