I've been reading the old threads and thought I had some answers but then I see a couple answers contrary to the others and I'm back to square 1. Here goes:
1. Do the good furnace filters (3M ones) filter well enough to not need an exhaust to the outside? (ie like my stovetop filter that doesn't vent to the outside) I don't have an easy way to vent to the outside unfortunately (can't put a big hole in the wall to vent out of...) I was thinking of using twin furnace filters....
2. I have the
Caswell $200 collector, can I use it as the collector for my PC booth AND then move it to my blaster as needed or will I get contamination in my spray booth somehow?
3. If I can make all my walls, ceiling & floor metal in my spray booth, will that be the best way to go? (can I use galvanized metal?). Or just bend a piece to cover the 2 walls and ceiling?
4. How do I ground my metal walls in my booth? Do I put a screw in it and then run a wire from it to the ground in the power receptacle that my PC gun is plugged into? If not, how else do I ground it - I totally don't understand how to ground it.
My booth is 36"x36"x40".
Thx for any help!!
