Well after 10 years I guess things start to wear out.
My inner seals are still fine but the ones that keep water out when slides are closed are shot.
I've replaced the main slide seal now working on the kitchen slide.
Top seal on slide is in bad shape. The picture of the corner seal is how all my slide seals looked except for my bedroom dresser slide.
I can't believe how well the tape is holding up after 10 years.
I did buy a decal remover whee that goes on my drill to remove what doesn't come off when I remove the old seal.
