What are you planning to fill?

I'd say epoxy filler for the odd dent or scratch.

I've removed a blakes seacock and some of the gel coat has come away - i want to make it flush for when i replace - thanks

Best to apply at low tide.

You sure about this, I would have thought, for this job, a filler that went "off" and hardened quickly, better than a sealer that remains flexible

If it's for chips in the gelcoat, you cna get gelcoat filler. Plastic padding do one, works fine for me.

Interesting post, and I await the wise-ones' responses and advice.
May I ask for clarification? Do you mean "below the waterline" when dried-out ashore, or below waterline when actually "under water"?

Thanks.

"flexible" is a relative term.

When you come to remove the fitting you will understand.

Unless the holes are big, don't worry about it. The sealer will fill them and no water will get near. Belt and braces you might clean the area and apply a coat of epoxy , but I suspect you will find that the hole in the hull is just bare GRP. If the chips are outside the area of the sealer then an epoxy filler would be the correct one to use and then antifoul over it.

Marine Tex is what I would use but as others have said if it is under the lip of the fitting who cares and 5200 will do just fine.

MIND YOU WHEN THE NEXT POOR BUGGER TRIES TO SHIFT THE FITTING MORE GELCOAT WILL GO.

5200 is sticky stuff!

Yes below the waterline when afloat

I now realise that I asked an incomplete question. Doh!! Sorry.

What I meant was, "Do you intend to carry-out the repair when the boat is in the water?" : Therefore requiring a repair agent which can be used and will "set" while immersed?

I hope the error will not heap ridicule upon my head
