Using a solder pot

[[email protected]]

I read a great post about using a solder pot, but had a question. I
have a board that requires two components to be placed on the bottom
and soldered on the top of the board (an LED and a switch that are
panel mounted). Is it possible to temporarily cover those respective
holes with something prior to dipping into the solder pot, so those
holes do not fill up with solder?
Thanks,
Mike
