So the next step in my trailer restoration is to remove the old dry rotted non slip padding on each side of and on top of my fenders. The old was in such bad shape it came off but left the adhesive and a plastic film. Now I need to get that off and find replacement. Any suggestions for either removing and more importantly where can I find this non slip padding? I liked what I had which was black octagonal pattern but I'm having a hard issue finding what I originally had.
