I think I found one once but never saw that product ever again. It was a deep red, and not orange.

For fire rating?....not that I have ever seen.....For fireblocking, there is stuff you can accept as an "alternative" under 104.11...

My firestop guy says they are stupid expensive but might be worth it in oddball situations....Like $50 per 10oz. tube...

Even more expensive when you have to remove an incorrect product.

Reason i asked, i would think it would be appropriate to tell them what would pass when you reject their construction.
