Not sure that is a great idea Falcon- The isocyanate that is the catalyst in two part pants can be absorbed thru, the lungs (primary), skin and mucous membranes. It builds up in the liver and NEVER is broken down. You may not have a problem till years later when you get a primary hepatoma or liver failure. I think I read once that if you can smell it you are already 1000 times over the safe limit. Also a canister mask is like a superhighway to that molecule. Scotty
