An acquaintance of mine an old aluminum ladder, sort of like this one:
The ladder used to have some kind of rubbery strip at the forward edge of its top platform, to prevent it from scratching the wall when it's leaning against it. But - that strip is all worn out.
My question: What should I replace it with? I mean, obviously, some other kind of rubbery strip which adheres to aluminum, but - there's lots of kind of rubbers and adhesive strips. Is there some combination of materials, or category of these things which I should look for?
Also - should I look for something which comes with adhesive, or should I use use my own glue/bonding agent to attach the strip to the ladder?
