Mine only gets about 4 months of use a year, so I am hopeful it will last a long time. I do regularly use Areospace 303 on it to aid in the UV protection. I also use McNutt zipper treatment to keep them sliding freely. I haven't noticed any stitching damage yet, so I'll have to keep an eye open for that. Being it is an '09
I expect it has some life left in it yet. I always figured it would be the windows that wore out first in my case! So I try and take good care of them as we'll.
