What kind of epoxy putty is that? Is that the kind used for frags?

Yep, same stuff. I just painted over it after it cured. I've had the little rack in my tank for a few months now without any issues.

Just paint it.

My frag rack was made from a flat piece of acrylic with holes for the plugs drilled into it. It is easy to scrape clean with a razor blade if it ever gets crud on it.
