What about the Gougeon Brothers' recommendation that the deck core be sealed
by boring the hole oversize, filling with thickened epoxy, and then drilling
the proper size hole in the epoxy; before the bedding and backing?

The way I am doing it, right or wrong:
Locate your bolt positions and drill through the deck.
Set the fitting and tape around it with masking tape.
Remove fitting and apply a bead of 4200 around the perimeter of the
unmasked area and around the bolt holes. (5200 is to hard to remove
without damaging the deck down the road.)
Through bolt the fitting with a backing plate at least as large as the
base of the fitting. (I am using 1/4" 5083 aluminum because I have a lot
of it and it is easy to cut and drill.)
Tighten down the bolts just a turn or two past finger tight.
Remove the masking tape, clean up and let the 4200 cure for a day.
Tighten down the bolts fully so that the cured 4200 is in compression.

In my former life as a sailboat Captain [ that mean's I paid the bill for
the loan ] I never had to replace, rebed, or reattache, or put on new
.......... hardware. Things such as cleats, winches, etc.

Could someone tell me the correct way to go about doing this with a
fiberglass boat.

Say, a cleat. I understand that there must be a screw, or whatever that
goes into the deck to hold the cleat in place,,,,, what about sealing the
deck. And, on the inside of the deck [ below ] is there a backing plate
that the fastener of the cleat goes down through? What type of bedding
is proper.

Just a quick go through.

Thanks ,,,
