Anode bolt sealing

[cliffb]

I expect this has been asked a thousand times... but I can't find a definitive answer.
What sealant should I use on McDuff anode bolts in a GRP hull. Sikaflex? If so, what type? Or something else.
Many thanks for all replies.

Sikaflex is best. Can't remember the serial number, but the website should have it. Trouble is that the small tubes are hard to find, in fact I'm not sure if they make them any more. This means that you will have a big tube of the stuff that is guaranteed to harden up and be useless next time you need it!

Just remembered, it's 291

I have always used silicone without problems. This has the advantage that it can easily be taken apart when the time comes. You can also buy it up the "pound shop" or use up the stuff left over from doing the bathroom.

Wouldn't it be 292 for this application?

Sikaflex 291 I think.

MG Duff merely say to use a "marine grade sealant"

291 is for sealing 292 is for structual bonding.
