We have a simple surround with sligin glass doors. after 10 years of use the surround looks new but the sealing strip arround the glass has mold behind it at the bottom of the doors. Looks like the door can be disassembled easy enough -- has anyone ever seen this strip for sale? It holds the glass centered in the metal frame and seal it. There is a split at the top sp I know the total length just can't find it and I don't know the brand of door.
