"Pittsburgh" problems?

Anyone have fabricating debris problems with a temperer called “Pittsburgh” (Not PPG)? Upcoming CCU job, and I’ve never worked on this temperer’s product. Thanks in advance.

I’ve never run across them. I know many guys trust Guardian products but I’ve always felt the need to get the waiver no matter who does the tempering. Any company can have a bad batch and I want to be covered no matter what. I’d say get the waiver signed for you own peace of mind.

Agreed. Waiver is standard proceedure-non negotiable. Just looking for anyone with expierence w/ that temperer.
