    Will go for the 3M 4200. CT1 could not find it locally. Used 4200 also for the drain plug. Didnt use 5200 just in case i need to remove. I think 4200 for the deck fittings 9 bow roller etc ) should do the job. Re the drain plug ( Underwater ) do you think it is enough?

    Also be careful not to use a super adhesive urethane like 3M 5200 or sika 292, unless you're sure you want an incredibly strong bond.

    Silicones are for bathrooms and furniture detialing and suchlike. Not for the jobs you mention.
    Many thanks for the info.

    Sikaflex is pretty much the industry standard - I've used it for years and wouldn't use anything else now.

    I’m still a big fan of Puraflex PU40. Used it for years now without any problems, and a very good price from Toolstation.
