    I need to apply some external waterproof sealant to a metal fixing plate. Is there a special or specific type of sealant that workshops use for this or is a normal bathroom type acceptable?
    Thanks

    A cheaper alternative to Sikaflex that is just as good is Stixall, available from Toolstation for about £5 a tube (and free delivery on orders over £10)
