Hi James,
I haven't tried this, but I'd probably avoid gelcoat as it tends to be very brittle. I'd use epoxy thickened with microfibres or low density filler, then re-redrill.
I'd seal the screws with butyl tape. If you haven't tried butyl tape before then it is like a marine version of blu-tack - it never sets. It isn't great for items that have large loads e.g. cleats? - but for everything else it will keep things watertight for decades. Easy to apply - just use like blu-tack - pull a bit off, squeeze into a sausage and wrap round the screw. In fact I'd probably try butyl tape before I tried filling the holes.
Cheers
Martin

Hi all,
How do you seal screws which penetrate the buoyancy tanks (in a Wanderer Mark 2)? This applies to eg the screws for the swivel plates for the floorboards and the screws at the bottom of the tabernacle. I have a couple of screws which are loose in the fibreglass and leak air / water. Can anyone advise on the best way to recreate a seal? I was thinking about removing the screw, squeezing in some gelcoat and then re-drilling, would this work, and should i also use some sealant?
Very grateful for any views.
thanks
James
