I sprayed my 'glass coupe in my garage with a good BC/CC. I made up a plywood panel with two box fans mounted to it blowing outward. The air came into the garage through some furnace filters. The good deal about HVLP is that overspray is minimized.

FYI, box fans use inductive motors (no brushes), so they don't spark. The compressor is another animal. My compressor is at the front of the garage, and that is where the air inlet was. Apparently, the incoming air kept the fumes away from the motor - either that, or I was lucky.

The other problem is lighting. I had bookoo lights in the ceiling, and added a row of 2-tube fixtures on racks on either side of the car. I still had trouble seeing.

Finally, laying down a nice, smooth coat of either BC or CC isn't easy the first time out. The car in my avitar is the first one I've painted for more than 10 years, and there were some problems - not $15,000 of problems, though.

You can expect to pay upwards of $2,000 just for materials for a decent BC/CC do-it-yourself job.
