I've been benefiting from reading this site for last six months -- OUTSTANDING! This is my first post/question:
On a '79 S2 22 ft sailboat the toe rails have two channels to put chalking the length of the toe rails for the deck seal. Builder put calking just at the bolt holes which pressed out when tightened to about 1.5 inch in diameter seal at each hole. This allowed water to sit in the unfilled channeled areas between the toe rail and deck. When reapplying toe rail should I use butyl tape for these long channels or some other type of chalking and butyl tape aroung just the bolt holes as instructed by Compass Marine? Thanks for your feedback.

I would bed the entire toe rail in butyl and wrap butyl around the bolt heads before inserting them.
Just had my newly sealed chain plates survive about 3" of rain in a 15 minute period with no leaks. Tornado weather. I'm a believer in butyl tape.

If you have the time to r/r the entire toe rail I think butyl would be an excellent method to seal it. I also like the idea of sealing the bolt head and area under the rail.

The old Hunter Cherubini's used butyl to seal the hull to the deck and it is still plyable after 30+ years.

I also did my chain plate covers with the grey butyl and so far so good - the boat's been ucncovered for about 6 weeks now and I don't see any evidence of leaks.

It was too good to last. Found a small leak today. Just a drip but that's enough to cause a problem. Just port side, starboard is still ok.

Try snugging it up again.. Often seals it... If not easy to re-do compared to 4200 or 5200...

I just pulled it and used new tape.i think either I hurried the second chain plate when I first did it, or maybe it got hit with the pressure washer.
