Which paint product to use in this scenario?

I sprayed some 2k epoxy in my opened up longs. However, there is a boxed in section at the back that I could not get good paint coverage in. I think I have 3 options:

1. Use a rattle can with self-etching primer to hit the areas my paint gun couldn't reach.
2. Mix up some more epoxy and brush it in.
3. Brush in some POR15 (I used metal prep prior to painting and sanded lightly with a
Scotchbrite

I know POR isn't too popular and only mention it in case, for some reason, it's a good option in this particular scenario. The etch primer would be easiest. I'm guessing the 2k with a brush is the best option.

What say the brain trust?

Ended up going the epoxy with brush route. Seems to have worked well.
