Blakes seacock again

[westhinder]

I have had to remove a Blakes seacock from the hull, which went without problems, but what do I use to bed it with?
When removing the seacock, after 12 years in place, the bottom plate was covered in a soft, slightly sticky yellowy goo, which appeared to be a sort of grease. It was easily removed with cleaning petrol.
So what do I use to bed it on the hull? Try grease again? Sikaflex, which might prevent easy removal in another 12 years' time? Anything else? I have to add that due to the place where it is fitted, I will not be able to get leverage under the bottom plate with a screwdriver.

Many thanks

You will get every sealant in existence recommended.

I suspect (nearly) all of them will do the job.

I personally would use polysulphide sealant bought from a non-boaty outlet.

Thanks folks.
Will I be able to remove polysulphide again, or does it set and stay forever?

Yes. It will stay rubbery and the joint can be broken fairly easily.

Polyurethane (such as SikaFlex) is as you know a powerful adhesive, and very useful in the right places.

Silicone forms a very pliable and long lasting seal, but does not adhere so well to the surfaces which may be a problem if there is any movement.
