Ventilation for priming.

[Henry Rifle]

Way back in the past, I used an exhaust fan to blow paint fumes out of my garage when priming. However, I have long been nervous about that because of the possibilitiy of a spark from the fan igniting the fumes.

The last car I painted at home, I used two fans blowing into the room through filters to keep the dust out, and left a crack under the garage door for an exit. It worked really well.

I'm about to prime my Gibbon '34, and decided to use the positive pressure method again. I cut a piece of plywood to fit against the jambs in my garage side door, then mounted two box fans (pushing) on one side and filters on the other side. My only problem now is that the filters may be too good. They really cut down the airflow. When I do the final basecoat/clearcoat, I'm going to try to find a paint booth to rent.

Any thoughts on the setup?
