Thermotec and rocker sills

[rschiltz]

I'm reusing the stock heat shields and noticed I had a small hole thru one side where an exhaust clamp poked through. I patched it from the outside with a 1 by 1 in. piece of Thermotec be cool.

I've read some horror stories about Thermotec, think I'll be ok with this small piece?

I would remove it except I already reattached the shield to the rocker.
