Will this fix a Crack in the standing shower base? Or a plastic piece for the fridge shelf that's a hinge piece?

Something like T-Rex Flexible Waterproof Tape would be good for a Crack in the standing shower base.
The plastic piece for the fridge shelf that's a hinge piece you will need some type of glue as this is just a silicone sealant.

Yeah that's true if you have a big job to use up most of the tube but I like to have these small ones on hand for small tasks and are easily resealable.

Its a shower base pan like this: https://www.lowes.com/pd/Sterling...6jEALw_wcB


The crack itself is about 2-3 inches on the curved part and I did put a "tape" made for it but I noticed that its lifting....dont know if water is getting in there just yet and if any its minute. I read that I'd need to sand/fiberglass a fix....do you have a direct link to the tape you noted?

The drawer cover for the fridge has little tabs that it hinges on to open/close and its broken and instead of spending $70-120 I'd want to glue it if possible but other methods have failed and I might have to spend the money as its not just gluing it but also the weight that rests on the drawer itself that affects the fix.

Wish it were food safe... I could use one to coat a 3D printed object for coffee beans dosing.
