Hey Mikewarrior2, I find it very disturbing that they did not respond when you requested an MSDS (Material Safety Data Sheet). Email the bums back and remind them that they are in violation of OSHA by NOT providing an MSDS upon request. And no, they cannot claim proprietary ANYTHING as a reason for not giving you an MSDS.
In fact, post back if and when you do, and I'll help you give them a hard time.
