What is the purpose of Jute like padding behind fender on firewall

[ramchol76]

I'd think that would just cause more rust issues. Jute just sucks up moisture, and holds it.

agree... mine soaks up water coming out of cowl drain and seeps into passenger side carpet area (through some gap behind fender)... that's why I am exploring this area.

Weird, never had any water or moisture issues inside mine.

I can see the jute sticking into the front door jambs when I open the doors. I'm sure that area sees water especially when I run it through the carwash about once a week
