Who knows what this part is called?

The felt insulator strip on the upper firewall, 19 Tundra.

 

Gotta pic?

 

What happened to it?, That's the same area critters like to chew on for some reason, and even had reports of some fires there.

 

Yea something got on top of the brake booster and had at the felt.

 

Yup, Friggin mice it looks like. Do you want to replace it? I've seen a lot worse then yours, maybe you can blend in the affected area to make it look fine, and then proceed to a game plan to keep the bastards out.

 

This is the closest I could find. But I didn’t think it was as big as it looks in this picture.

I have a ultrasonic unit plugged in and running in the engine bay, I was thinking just hit it with some black spray paint, but it bugs me, more ocd than I thought I guess, lol

 

Don't feel bad, it would bug me too.
Even though I'm the only one that would ever see it...
