This is the air filter that allows fresh air, that's clean, to be drawn into the paint booth. I have a fan on the other end of the paint booth that draws air from the booth and blows it outside of the garage. This filter is just a cheap furnace filter that I taped in place in a hole in the plastic jacket.
Here are my paint booth supplies. I have a plastic trash sack, a roll of paper towels, a 1/2 gallon milk jug for mixing paint, funnel paint filters,a plastic funnel, the paint, a can of acetone to dilute the paint for spraying, the spray paint pot, the air hoses, and the spray gun.
Here's the belly of the tub, all primed and ready for yellow paint.
One of the real challenges of painting the top part of the tub was trying to get underneath the edges above the rear fenders and up behind the dash panel. To paint behind the dash panel, I tried using some of the holes in the firewall to spray through. I'm looking forward to getting some yellow paint on it, at this point.
Here's a bunch of miscellaneous small parts that I painted last fall, including the drive shafts, the air cleaner, and some universal joint u-bolts.
Here I'm starting to paint the inside front of the tub. Trying to get up under the dash to get good coverage was really difficult. I was very glad that my spray gun was not attached to the paint pot. This allowed me to paint at awkward angles. Hey, who is that in the tool box that keeps drinking all my yellow paint!
The paint here is going on very smoothly and I am getting good coverage, especially where the sheet metal is smooth and flat. I also very glad that I have a full, polypropylene paint suit and a good respirator to keep the paint off of me. Except, I had to shave my beard to get a good seal! I still ended up with a yellow chin.
