Thanks to all members contribution on this subject,I think for small
localised I would go with the bent nail idea for cleaning out fixture
holes and then fill with epoxy resin.Mike Capels way off taking off
the top frp skin makes a lot of sense as working from below the deck
head would be messy,Mike would you reuse the outer skin after grinding
back the underside, this can the be bedded into a epoxy putty and I
thought vacum bagged down grind down seam where cut has been made and
fill and paint a big job but as you say doable It seems quite a few
deck fittings that had not had predrilled holes bored oversize then
refilled with solid laminate has caused a lot of these core problems

Jon,
I’m not sure if I would re-use the pieces of upper deck laminate that
were taken off. Problem is, you need to get a strong enough bond
between the still remaining layer of upper laminate and the pieces you
put back. This means you have to glass over the seams, not just fill
them. The stiffness in the deck comes from two layers of laminate
spaced evenly by core material and bonded to that core on both sides.
It might well be easier to just put on new glas and resin over the new
core material. You will have to paint the deck anyway, and with the
old deck pieces put in first you get a lot of build-up of glass that
has not much positive effect on stiffness.
Hope this helps.
One other thought: if you would be able to open up the space between
the two layers of laminate from the side, instead of from the top or
bottom, and if you would be able to get out the wet core material from
the side, i.e. from inside the cabin, you could perhaps foam in liquid
uncured core material. If you find a foam that hardens to a solid
enough material, this could well be enoug to keep the two laminates
separated and the deck stiff enough. This would save you a lot of work
on the cosmetics. Just a thought, dunno if it’s possible.
good luck,
Michel

I’ve found using a dremel tool with a small router or grinder bit works very well and is a bit quicker then the bent nail. It won’t work for very tiny holes but 1/4" and up does well.
