First, I believe that epoxy to epoxy (even if 1st coat is fully cured) DOES make a chemical bond, as long as amine blush is removed.
My gut feeling is that you would get a better bond if you coat before full cure. But I'm not sure it's practical, because my ideal is to fully coat all components before assembly, so they're better protected from water. It would be hard to do that, and then assemble before cure.
I've used CPES to protect various things, and didn't see the blush. I wonder if it doesn't tend to blush, because it sinks in so deep? Also, I understand the blush is from humidity - work in a dry environment and it doesn't happen?
