Need advice/ opinions on slide out repair

[RVRoadrambler]

We have a 2016 3711fl with the opposing slideouts for the living room area upfront. After 8yrs of full-timing we discovered that the material used for the underside of each slideout is different. One is slick surface & identical to the tan color used all over the rest of the rig while the other is more like a textured black plastic.
I never understood why they were different but I think I got that answer covered on another thread.
Anyway, upon arriving at our current location we discovered that the tan flooring incurred an indentation right about where the nylon roller sits when the slide is retracted for traveling. In an effort to try and avoid replacing the entire floor of the slideout I'm considering trying a repair and enhancement to it to see if it will work but, am wanting to gather some opinions about my idea first.
I am considering purchasing a couple of 1/8" thick by 6" wide pcs of UHMW either in tape form with adhesive on one side or just sheet material to run the depth of the slide where the rollers track.
My questions are:
1. Is this a feasible solution? 2. Which product do you think would be the better option and why?
I'm not crazy about the idea of mechanical fastening with screws underneath there but for some reason feel like the sheet might be more rigid than the tape even though it's the same thickness? I don't know, but those are the questions haunting me before pulling the trigger. Hopefully someone has some experience and can help me out here.
Thanks
