Well, it did melt. It didn't even take very long. I am not too surprised given the $9 delivered price tag. On the plus side, I have backup set of mounts for my redneck exhaust hanger bracket.
I have this on hand, and it won't melt. It's just not much to look at other than being carbon fiber.

I am going to put some of that heat reflective tape on the back side of it just to hopefully make it more effective and last longer.
