If I wanted to make a heat shield, in custom shapes and what not, what materials are suggested? I'm looking at building one for over the turbo and possibly a couple other spots. Something that can be shaped like fiberglass and is not going to burn or melt would be ideal. I want to keep away from metals as much as possible too.

 

All I could find..
