I am getting ready to buy a Bed Rug but have a question or two for anyone that presently has one in there bed. Will the paint in the bed below the rug get scratched from the Bed Rug? Also will water get in between the Bed Rug foam and the actual bed like it does with a standard plastic bed liner? My bed is never used and I don't want to have the Bed Rug mess the paint up or trap water and rust the bed out. I like the look of the Bed Rug but don't want to mess the truck up just for looks. Thanks for any help anyone can provide....
