The top left curve of my rear window is coming away. (see picture below) I can see that the previous owner has put some black filler/sealant stuff on the top right of the rear, in the past to resolve a similar issue.

Does anyone know what this sealant stuff is, or can anyone recommend a product I can use to reseal the window to the surround? Or is there another way to fix this which can be recommended?

There are 2 failure modes on the rear window to be aware of besides the broken clear plastic:
  1. The stitching that holds the window zip in place rots and the zip falls off at the corners. Either hand stich the zip back in or replace the top.
  2. The black rubber bead comes away at the corners. The bead is part of the window and provides a seal. The usual fix if you have an original top, is to buy a replacement rear window and zip it in. Check the condition of the stitching as per 1) above first. Be frugal with the application of sealant in the attempt to fix the bead rather than replace the window. You'll have to deal with removing the sealant at a later date when you finally replace the window. If you are planning on replacing the top, then apply as much sealant as you like.

I have this same issue!
At first I managed to tuck it back into the beading using a credit card, and was very pleased with myself!
Alas, as soon as I lowered and raised the hood it’s all come away again…I’ve just ordered some storm sure sealant to put behind the trim, and re tuck it in…hopefully it will stay put!
