What's the problem your facing? And how far into bloom are you?
Azamax is basically a concentrated version of neem oil, so I wouldn't say it's really any "nastier" than neem, just stronger. It actually leaves less of an oily residue than neem, but still has a strong smell (can't comment on taste, thankfully).
We can give you better advice if you tell us what the problem is.
I can tell you for sure you don't want to be dunking a flowering plant in water. That's a bad idea.
