Isn't there an explosion hazard running the box fans in all of that overspray and flamable vapor?

I just shot this mustang hood in single stage and topped it with some clear.

I don't want to be in the minority, but I was also going to wet the floor until I read a post on another board. The idea was it added a lot of humidity to the space just as you began to spray. Most of the trash comes from your clothes,the gun,the hose,out of the air supply, not off the floor.

I painted my sons Challenger in our garage by framing a paint booth out of 2 x 4 and stapled heavy plastic to it and had plastic on the floor.

I built a box at one end of the booth that faced into the booth and put furnace filters in it. on the outside of the box I cut a hole large enough to put my leaf blower through and tied it so it would blow into the box. The air would go through the filters and be clean. That would presurize the booth. At the other end I had a row of furnace filters that the paint dust and fumes would pass through. This kept the both clear so you could see. I got some 4ft shop lights and a few halogen lights which were installed on the outside of the booth shining into it. This setup worked really well. The lights on the outside were for safety of not having the place blow up.
I used a couple of moisture filters on my air hoses cause water will form in the hose as the air cools. a couple filters in the line are cheap insurance.
Hope this helps.

I was also wondering about the humidity issue. The paint I have does specifically warn about humidity.

I installed fan and filter system in my window and my door. I'll give it a try tomorrow when I spray some more parts and see how it goes. Thanks.
