[C320-list] 3M 4200 fast cure

[jim brown]

On our boat (hull 978 2004) the shrouds are attached to a plate on the deck with a welded "eye" on it. There is an identical plate inside the cabin thta the rod attaches to. The two plates are held together with four bolts that go through the deck. I haven't removed them yet but I don't think that the plates themselves penetrate the deck, just the bolts. I think (hope) that with the two plates bolted together that adhesion won't be needed and that the tape will provide a flexible seal. Fingers crossed. The youtube piece from Sailrite and the youtube piece from Compass were very helpful-thanks. I can see a lot of uses for this stuff. 

Jim

If Jim is referring to what I call chain plates (thingies that penetrate the
deck and attach to the ss rods in the cabin,) then I don't think butyl tape
will work for that.  I'm not even sure 4200 is the best.  On the advice of
our marina I used BoatLife LifeCalk about 8 years ago and they are just
beginning to leak now.  There may be even better products out there now by
Sylkaflex, 3M, and others.  The qualities needed seem to be: strong adhesion
and flexibility.  
Jim doesn't say what year is his hull; but, if it is an early one, it might
be a good idea to remove 1/2" of deck core and replace with filled epoxy to
prevent water entry to the core.

I use butyl tape for anything that requires a water tight seal but does not
need adhesion.

For what its worth, I've picked up 4200 at Walmart before (and its less
expensive).
