I was cleaning out the inside of my car took off the seats checking for rust and as I was doing so I found on top of the floor pans there was hard rubber that seems to be stuck on top of my floor pans and in certain spots at the edges you could see small rust spots. My question is should I rip off this rubber to get to the floor pans to see if there’s any more damage? I posted soon pics and I put a screwdriver parsley underneath the rubber to show what I’m talking about — At first I thought it was the metal until I found out that it’s molded on top off the floor pan kind of like a sticker
