Re-bedding / sealing deck fittings

[Big-Bang1]

I know this has probably been done to death but... I have a Channel Island 22 with leaks. The grab handles on the cabin roof and VHF aerial base are weeping water in. I've dropped the headlining ready but don't know what sealant would be best. I've been advised to use everything from CT1 to No more nails
What do people use?

Personally I would not use an adhesive sealant which CT1 and No More Nails are. Review this article which is about sealing deck items. Bedding Deck Hardware With Bed-IT Tape - Marine How To

The buy some butyl sealing tape (which Bed-It Tape is) in the UK (I assume you are based here) and mould to the desired shape as per the instructions in the Marine How To article.

This butyl tape would do the trick, but search around for a good price PSP Tapes Butyl Sealant Tape

I use Butyl in a tube for all my fittings above and below water. Can be messy but things don't seem to leak after use.

I’ve got a CI32, butyl is the answer.

This is Butyl in cartridge form. Ferociously sticky but not adhesive, lasts in the tube:

Thats the stuff !

I've used Butyl tape for numerous sealing jobs on board. Deck fittings, window sealing, etc. All successfully. And you can remove fittings easily in the future.

That's brilliant, thank you for your replies and advice. Looks like I'm off to buy some butyl

Mask the area of round the fitting before using the butyl !

Top tip, thank you!

Don’t forget to put some under the screwheads as well as around the base.

Another tip - after refitting don't fully tighten down the fitting straight away- it will probably squeeze all the sealant out- leave it to harden off a bit before final tightening
