Fridge liner crack repair????

It would appear that a bottle, or something hard, took a nose-dive onto the lower portion (shelf) of the fridge. I found a small, half-moon shaped crack when giving it a cleaning. I was able to "push" the outer edge down, which "popped" the inner portion of the crack back in line with the rest of the liner. It is a hair-line crack, so I don't think any cold air will escape. I am concerned that it could be pushed down again, or eventually lead to a hole in the liner.

I did a "crack" "fridge" "epoxy" search....came up with nothing.

Anyone know of an epoxy that would not make a mess of the fridge. The crack is hard to see, don't want to replace it with a big, ugly, patch job.
