The vinyl on the edge of the door can be "stetched" a little with a just warm household iron, take the door off apply the iron flat to the edge and tease the vinyl back to the edge pushing with the iron. becarefull not to apply too much heat or the vinyl will shrink even more, if you can get it back over the edge of the door run superglue along the edge for a long term fix. i doubt the vinyl is discontinued large manufactures normally discontinue a line before the vinyl maker does, it may be possable to source a new door from another retailer.
