What about just using orings? should be easy enough to size, and placing

the drilling one at a time sounds like a good idea to me) Neoprene
orings should survive well, but maybe I am missing something?

I've thought about that as well. It seems to me that using caulk to try to seal
something that moves around even a little bit is a temporary solution at best.
I've now got numerous small leaks in the deck of my boat which showed up only 2-3
years after being re-bedded by the PO. It would be nice to fix these in a way
that didn't need to be redone every few years.

I don't have a solution right now, other than to point to the sealer washers around
the screws on my metal roof. A roof is exposed to terrific heat during the summer and
it gets flexed slightly by the wind, and even hail yet maintains a watertight seal for
decades.

And Wayne: The fact that boats are usually not done that way _can_ be an indication that it
isn't a good idea, but...

Anyone have experience with using a sealer washer to seal around the bolts and screws that
pierce the deck on their boat?
