As far as I know the paint is a single stage. It uses a activator.
The paint has been drying for 2 weeks so far.

The door into the painting room might be where the dust is getting in. It is a sliding sheet of 5/8" plywood and doesn't fit all that tight. The room next to the paint room is used for motorcycles and snowmobiles but nothing going on there while we were painting.

We did wet down the floor but the point about not moving around too much is something to think about.

We have a fan mounted about 4ft from the floor on the back windows do you think making a adapter and mounting a large diameter flex hose and having the end down under the car would help.

thanks for the spiritual advice
