I hate to tell you this but damn near every astro roof slider Iv'e ever seen has had the material coming off it. My friends 7,000 mile GN even has the material loose on it. Iv'e had a 32,000 mile GN and now have a 37,000 mile GN and both of them have the material loose and coming off the slider. I do have the slider as I said and any decent upholstery shop can recover one for you.
