2017~2024 Sound insulation underneath the CX-7

:
Mazda CX-5 Grand Touring
Impressive what lengths Mazda went through to insulate road noise. I haven't looked under a Lexus, Mercedes or Jag lately, but I was surprised to see sound insulation underneath our truck.



I can't imagine this will hold up well to the elements of cold snowy winters, rain, freezing, road debris, hot humid summers, repeat...

I'm chewing on options that I can spray on it to give it more durability.

Suggestions?
 
Truck?

CX-7???

You need to post where it belongs.
 
Suggest leaving it as-is to see how it holds up before coating it in anything.

It's the same material now being used in wheel wells of some cars.
