I have heard of someone pulling up their carpet and finding a STOP sign!! Haha! And, I've found my carpet wet a couple times, and took a closer look at my floor. Yeah, it's kinda crappy. I spent some time yesterday looking for my rear hatch speaker wires that were in the LR quarter panel behind the spare tire. The bracket for the tire came right off the floor when I pulled the top bolts out. I could see pavement...Sometime this summer I'll pull everything out and find the worst of it and patch it up. I would imagine I'll use some light steel and mold it if I have to. Pop rivit and seal it in. Primer it up. Put some more insulation down and throw the carpet back over it. Undercoat it on the bottom. This is similar to what GoSlowGetStuck did with his. It turned out nice.
