A crude attempt at making a portable spray booth is posted on ABPW.
Haven't put the plastic on second panel or floor yet, but plan to give it a
trial run later today.

Michael Dresdner made a folding haevy gauge cardboard three
sided spray "booth" with a hole in the bottom rear for a big
window fan. He puts it up against the inside of the garage door
and opens the door just to the top of the fan. Folds up and gets
stuck in the rafters when not in use. Check your local
box supplies outfit. 4x8 sheetsa are about $4 each in
bundles of 10. What you don't use for this thing can be used
for full size mock ups of furniture ideas.
