My hardshell bag was slit during handling - 2", sides could be fitted together. The shell has give in that spot. Will it hold up to baggage handling?

If the hardshell has some good years of use ahead, I would give it a try. My experience with the product is that it held up very well in repairing a cracked door that gets a good deal of use. How it will hold up depends on how well the material is applied and how much rough handling the bag gets, among other things. Good luck.

Is this product heat resistance? I need something to repiar holes in a plastic solar water heater

I used this on some hub covers of my truck lug nuts. it is very hard when cured. Only good if fresh shelf life bad. make sure you ruff things up to bond to your piping or what ever.

can this be used to fill in deep scrapes in a bumper?

I don't think I would use it for that. This epoxy will harden to a durable hard plastic, much like ABS. Although it does have some elasticity it's really designed for more rigid applications than a typical bumper cover. This is great for repairing things like cracked or broken plastic as might be found in car dashboards or appliances. It could even be used to rebuild areas that have missing areas.
