Anyone have /or have had this problem?

Leave the bench where it is and locate a table near an exterior door to do your spraying. Vent out the door, maybe make a device that would fit in the door when ajar, sealing off the outdoors but providing a port for the booth to vent through. Hard to say since we can't see the room set up you have.

One option is to remove a pane of glass (one of the cracked ones?), and replace it with wood, that has an opening cut into it for the air duct tube.

 

 Ditto to BSpeed's reply.

Thanks for the suggestions.  I am working in front of a single french door, but the problem is that the skeleton lock is frozen shut and I am not able to open thje door. All the cracked panes are in a room I can not use. I am almost to the point of cutting a hole through the wall or ceiling to vent.

Do you rent or own the house? Is there a basement? Second story?

We own the house and are remodeling. The basement is just a hole in the ground more like a root cellar/crawlspace. We have a full walk up attic completely unheated and with no AC and a long way from being remoldeled. The only way I have been able to panit is to drag everything outside on the side porch. With the Temps dropping this is going to be a problem.
