In these pictures, I've used both 40 and 80. I don't paint, but that's not to say you couldn't use Krylon Fusion beforehand (cures reefsafe IME). Cure time is as per manufacturer's recommendations.

Pretty easy. You lose your coralline often, but it's a minor nuisance at worst.

If so, what is it and how long a cure time?

Just regular concrete. I cure in tank once it sets up if there's less than ~1 cup/100 gallons of tank volume. If there's substantially more, I cure for two weeks remotely. Ideally hydrated for max strength.
