One of my contacts at the body company that builds the bodies for these type vehicles hooked me up with 4 partial scrap rolls of this stuff. My plan was to use this as a makeshift bed liner/vinyl wrap. This stuff is UPS brown but would have looked alright on a white burb. I think I may still use some of it to lie on the door sills.
Something I undid and the re-did on my Suburban may work well on yours. My Sub had pieces of anti-slip tape on the door sills. I was doing something and removed it from the passenger sill exposing brand new looking paint (they had been on there a LONG time, but I am not sure if they were oe or not). Anyways, as time went on, I began to think that was probably a good idea to have that on there--especially with the truck being lifted a bit. I started searching for it and could not find it anywhere. I was at a rental-property supply warehouse one day talking with the cat who knows everything and I asked him if he had this stuff--like self-adhesive sand paper. He said he didn't but what about a skateboard shop--the grip tape used on the top of the deck?? Ding!! What a great idea. Five dollars later I had what I needed.
Now, when I laid the first piece out I stopped an eigth of an inch inside of the edge of the sill (right before it drops down toward the rocker panel). It works good, but when I re-did the driver door and third door I wrapped the stuff OVER the edge so it goes down the edge and eighth or so. What a difference that little detail in running it over the radius made!! Once you get your shoe near it, it has traction right now. Amazing. The only drawback is if you run the back of your leg down it during egress. I thought this would be an issue, but I have yet to do it and the traction tape has been on there for a year or so, so I would say that the risk of that happening is minimal but the benefits far outweigh the risk in my opinion.
Now I find the stuff at Lowe's and Home Depot in their safety aisle. Figures.
