Well your doing a great job. I'm painting mine in my garage. I have a home made exhaust fan system. The new guns use less air pressure, less paint and atomize exceptionally well resulting in very little paint dust. And then your sanding & polishing as well!
I hope your using a good mask. Make sure people don't breath in those vapors. I did a lot of work with bad chemicals when I was a teenager. I guess it's possible I contracted PD as a result. Better safe than sorry.
