I recently had this seal leak, the glued seam came apart. Looking for what glue comes in the universal oring kits I found this Loctite 401 Material insensitive glue. It seems to be holding well.

 

I replaced my sunroof seals yesterday with Britpart ones. Yes, they look backwards when taking out of packaging, I just twisted mine and they were in the correct orientation . I did find though, my sunroof trays are a little warped (25 years old) and still have a slight leak with new seals. Going to warm up and try to get the warp out of the trays, and look for a couple more locally to see if they are any better.

 

Nice to see you on this forum as well. There are several BC Roverlanders here.
