Sikaflex

What if any are the plus points of Sikaflex over ordinary silicon sealant?

Sikaflex is not silicon sealant, it`s polyurethane, it uses moisture to cure. Silicon, air dries and gives off acetic acid as it does so, which corrodes things. Use silicone in the home, it has no place aboard a boat. It is also agroscopic, which make sit absorb water, which also makes it useless aboard. Also sikaflex is very much stronger, as a bonding agent.

You could aslo use Grenville PU Flex which is a polyurethane sealent. About 6 quid a tube. Comes in grey, white and black. Not as much money as pukka sikaflex as its not aimed at the marine market.

As it looks as though most of the fittings have been attached using silicon sealant could this be some of the reasons for leaks? Also I have noticed that the silicon peels off very easily if it is wet around it.
