I'm a fan of the butyl tape. I used it to bed or re-bed everything above waterline on my '74 M17. Soooo much easier to work with than glue/caulk type products, whether hardening or non-hardening. And yeah DO NOT use silicone! cheers, John On 9/16/21 8:14 AM, Dave Scobie wrote:
No bedding compound is forever. Dolphinite is a fine 'old school' bedding compound. I prefer Sikaflex 291 or 3M4000/4200. Some like butyl tape (not my favorite choice). DON'T use silicone nor 3M5200!

Dave,Thank you for the excellent guide. I just ordered some dolphinite to bed the hand rails on my M17. Would you use 4200 instead? It is mostly garaged but I don’t want any leaks when I’m sailing. I assume 4200 is more leak resistant.

Hello fellow Monty owners, first off, I apologize for having to register a new account on the mailing list, somehow my old account seems to have been bungled up and I was not able to recover it. I have two new maintenance questions: a) The rudder on my 1982 M-17 is the one-piece solid mahogany style. When I got it with the boat about 10 years ago it was wrapped in fiberglass, and coated with a couple of layers of some marine varnish. This summer I kept the boat moored in fresh water, and last time I went to it I noticed that large parts of the fiberglass were peeling off. Is the fiberglass needed, or should I just remove it and re-coat the wood with varnish? If I need to redo it all in fiberglass, what should I do to prevent it from peeling again? b) I have a small leak into the cabin around one of the screws that holds the wood hand rails on top of the cabin. I understand that it is important to re-bed the hand rail before the moisture gets inside the balsa core of the cabin top. What is the procedure for doing that? To begin, how does one remove the small wood caps that are covering the screw heads, without destroying the caps? What material do people recommend for the bedding procedure? Thanks,Andrei.
