I have a bedrug has anyone had any experience with this? I have had bed liners before and as long as you don't park the truck for any extended period of time the liner keeps moving and keeps the rust away. I have seen the whole bed wherever the truck bedliner touched just after a few years it was all bare metal but no rust. Just throw it back in and it sorta takes care of itself but I would go for the pad also depending on whether you are putting a tonneau cover on or not.
