Thanks for the write up. This gives me the confidence to do mine. Last winter I noticed some moisture in my carpet and I suspect I have a hole somewhere down there. I haven't pull up the barrier to check but I did notice a crack in it where my heel pressing the accelerator rests.

Once I get my suburban back up and running I'm going to tackle this issue on my SD.

Where did you get your POR from? All you need is the metal ready and the sealant stuff, correct?
