I thought I mixed it thoroughly, however if I didn't, then you would think the entire batch would be bad, but it's only a few isolated spots

Not necessarily.

If you have missed scraping the bottom, sides and corners of the container as you stirred, then most of the mix could be fine.

I have not had any badly mixed epoxy applied to a kayak, but i have noticed sometimes when there is a little bit left in the bottom of the container, that it has all gone off except for a very tiny bit in the corner which was obviously not well mixed. It takes a lot of scraping off the walls of the container to ensure that all of the mixture is properly combined.

If you had scraped such a badly mixed bit out of the container with your brush or squeegee, then you would have a bit that wouldn't harden properly.

So the clue to avoiding the problem in future might be as simple as being really careful about scraping the sides, bottom and corners as you stir.

The solution to the current problem is a bit more difficult, but you may be able to carefully use a heat gun to soften the epoxy in the bad bit and slightly beyond. If you carefully cut a circle around the bad bit, you may be able to peel it off once it is softened. That would just leave a small amount of sanding of the hardened epoxy around the perimeter. Then apply a patch.
