Not yet, but I have one of mine that needs replacing. It is the rear seal on the kitchen slide-out. It looks as if the seals were fitted before the slide was installed so there is very little room to get at it. On mine the top 3 feet of the wiper has pulled out of the retaining seal and I don't think I can re-insert it. I may replace it with a different seal that can be fitted from just one side.
