[Public-List] Which caulk for cockpit teak combing joining to fiberglass?

[jreadams6]

I did what Mercelo did with the D shaped seal and also used caulking. It
still leaks enough to need some caulking maintenance this year - it leaks
in an area that got bashed in a jibe, so maybe not the seal's fault. Some
comments on the other posts:

1. Oak is much cheaper, but does not wear well at all and is hard to
maintain - it is a hard wood, with ridges that collect water, dirt and
ultimately mold. Many people when using Oak in furniture will fill the
ridges with a filler befor finishing it. I have seen boats that use oak and
it is not pretty over time. You could probably use a different wood that
would not be that much more expensive - mahogony comes to mind.

2. On leaving a gap with washers, this is interesting. On the  one hand it
keeps the area under the wood from getting wet and staying wet - which
makes it impossible for any varnish to stay on. However, then your butt
gets wet when you are sailing in weather. I know Wes did away with the
coaming, but he only ever sails in the Severn River. The Alberg is  wet
boat upwind in any kind of seaway and breeze. The water sprays up on the
windward side, and then rolls down the deck to the aft end of the coaming
and from there can make its way to the lee side. Along the way if it can,
it will try and get into the cockpit.

My $0.02.
