2 part epoxy questions

[gregzz4]

Not knowing whether I should pose this here or in the Tips and Tricks section, but here I go ...
I have South Seas Base Rock. It's dry and clean. I drilled it and stuffed acrylic rods into some holes, but didn't like the stability, so I then bought some 2 part putty.
I soaked the rocks in water, applied the putty, and let it cure for more than the 4-6 hours recommended @ the required temperature. Everything seems to be solid, but now I have a potential issue ...

Do I have to keep it wet, now that I have stuck it together?
If so, looks like I'll have to buy yet another rubbermaid or 2.
