Can I use this to seal a crack in the seal of a double wall metal water bottle on the inside so I can use it again?

As far as I know its food safe. I'm not sure about sealing a water bottle. Its supposed to seal everything ! Its a top of the line sealant.

I want to seal some cracks on the outer edges of my concrete bird bath. Is this nontoxic and safe for birds?

Yes, this product would be safe to use around all foods.

can this be used in a vegetable garden planter where it will come in direct contact with parts of the plant including the vegetable/herbs and roots?

Yes, your application will work for this product. Best of luck with your project!
