[Rhodes22-list] centerboard repair - cap sealant? reply to Saroj

[Lowe, Rob]

Saroj,
Hey, good to hear from you again.  I was wondering the other day if you
were still around.

I can't add much to what Ed said either, but I think it's 3M 4300 he's
talking about.  I've had good luck with GE's Silicone II (Lowe's or Home
Depot) for underwater repair on my hot tub.  Look for something that
say's it's good for aquarium repairs.  That's made to be used
underwater.  Also, it's sound like the blue stuff you found was RTV.  

- rob

Hey Saroj,

I don't have anything to add to Ed's response, which I think is
right-on.
But welcome back to the conversation, and thanks for adding a new topic!

Saroj:

As to sealants, do not use 5200 like some boat builders.  It is called
sealant but it is permanent and prevents future repair, painting, etc.

I recommend a sealant that says for under water use.  3M 4000 or 4200
are
numbers I can think of quickly.  Go to the 3M website and see which one
is
for underwater use.  (I know the cap is not underwater, except at times)

Another popular product is Boat Life Sealant, not Boat Life Caulk.

As to silicone products, make sure it says for underwater use.  Silicone
II
is said to be the better formulation of silcone sealants.  

I would not go to Lowes.  Go to any dockside marine store or if you have
to
the high dollar 'West Marine'.  It would be better to pay the few extra
schekels at West to get a quality product.

As to screws and bolts, Stan uses a million bolts at the shop.  Maybe
older
boats had a mix, but I would opt to go to thru bolts, all one million of
them.  Also, after you tighten all the first time, go around a second
time
and maybe a third.  A small 1/4" rachet works for this job.  If you do
not
have one, head for Sears and get a Craftsman set.

It is good to see your post.  Are in in contact with any other
'Tidewater'
Rhodies?
