s.s., There shouldn' t be any reason you can' t get the limbsavers to stick. Your limbs have to clean. Any of that old epoxy or other crap you' ve put on there needs to be removed. Next you have to make sure you find a fairly flat spot on your limb. They will be ok on a slightly rounded area, but not any with an angled creese. Wipe down the spot with some denatured alcohol. Don' t just use the stuff laying around the medicine cabinet. After it drys, stick a new limbsaver on. Press it down real good, all around. Next take a sharp edge, like a knife blade, and scrape the perimeter of the plastic. You should be able to tell whats been scraped vs untouched. I have some that have been on for years. They should stick, if they don' t, call or email Sims.
