I don't believe any of the stabilizing agents are safe to use without fresh air, supplied air. I used to know something about xylene, not popping to the top of my head at the moment. I want to say it was a highly dangerous ingredient in some paints such as the three part paints that used equal parts of paint and "hardener" and roughly an equal part of thinner. That info is a little shaky but what isn't shaky is all of that shit is dangerous as hell!
I was using Ditzler products when their high epoxy paint came out, Deltron? similar to Imron. I talked to the factory at least once or twice a week for about six months. Talked to one engineer who I thought I knew well. He told me the double bugeye organic vapor face masks were plenty adequate. After six months my shop foreman and I who painted cars together, were both having to sleep sitting up after spraying a car, breathing issues. I called to talk to the engineer and he was on vacation. Talked to a different engineer. "Oh, we don't let our people even mix that paint without fresh air."
There was something labeled as a respirator number on the side of the paint can, an OSHA number. I spent hours on the phone to OSHA. "That isn't really an OSHA number, it is a bureau of mines number." What the hell, I have ran this rabbit this far, I called the bureau of mines to find out what this respirator was. "The number doesn't refer to a respirator,"(despite the labeling on the can,Hu) "It refers to a pamphlet."
"What is the pamphlet about?"
"Fresh air systems."
While on the general subject, some people finish entire cues with superglue type products. His doctor told one cue maker that this was what was causing him to die. Second hand info, I wasn't in the doctor's office.
Lot's of dangerous stuff out there. Think twice before using it especially in volume. I went back to using standard wood sealers and finishes. I also turned a shaft blank from square to rough tapered in eight to ten turnings then a few more turnings to get to final taper. Out of a gross of blanks, 20-30% became finished shafts. I didn't see that the stabilizers upped the percentage a whole lot. Best I recall, less than ten percent more stayed straightish, and all of them sounded and hit soft. If somebody wanted a sharp sound when hitting a cue ball I couldn't get it with the stabilizers. I could get the medium hard hit I prefer so I used the stabilizers on3-6 gross of shaft blanks.
Main thing I learned about shaft blanks, they make damned good tomato stakes in the garden! Rows and rows of eight dollar apiece tomato stakes.
