Thanks, I actually purchased this material to make new kick panels for the front. I think it's a little too thick for the back of the seat which folds down to extend the deck area. The piece that was in there measures .05" thick but it pretty much desintegrated when I pulled it out. The same material was used for the deck area and it was pretty much dust when I removed it. I can see that it would be ideal for the back of the seat between the cab and the trunk on your car.
