headers wrap question

I just use header wrap in places that need some protection from the heat.
Like the 5&7 plug wire boots that would touch the header tube.
I folded it over twice making a 3 layer thick pad about 2 inches long with a little high temp RTV inside it to keep it from unwrapping and falling out from between the tube and the plug boots.
Basically just a high temp insulator pad to keep the boots from melting to the pipe.

Works great.
