dumb move? water pump

[optionizerSS]

So put the new water pump and timing cover on the other day and today noticed a leak. Looks like its coming from the one bolt at about the 7'oclock position. I failed to put any thread sealant on any of those bolts. So if I pull that bolt back out what is the best thing to put on those threads considering the threads will likely be wet with anti freeze?

Ended up pulling the water pump back off and reinstalling. Not sure what happened but seems to be ok now.
