Bedliner
Yes. I had rv I made. Shower was hardboard dryerase wall.
I rolled on cheap truck bedliner.
Gray was a nice color.
It is sticky enough for wet feet and thick to cover every.
After 3 months still looked beautiful. It was on floor and 5 inches up wall.
Bad driver hit me so i got a big check. Im sure rv went to junk yard so idk long term status.
