Important to know the diff between 3M 4200 and 5200, if you choose to use them. This has it in a nutshell: https://sailanything.com/post/48445963210/4200-or-5200-what-should-you-use Internet search on 3M 4200 vs 5200 will get you that and a bunch more info. And, for everything above waterline, I would use (have used) butyl tape, myself. I've helped people mess with 3M 4200 and it is just dastardly to work with. Also, 4200 it is "removable," but not as easily removable as butyl tape. cheers, John On 6/14/21 12:08 PM, Bob Eeg wrote:
Silicon is very bad advice. The only exception for me is the windows. I prefer BoatLife Caulk, 3M4200, etc. never 5200. Bob

Please don't use silicone nor 3M5200 on the boat. (On a Montgomery/Sage there is ONE exception to the silicone rule.)
No worries about me using silicone. I hate the stuff, both on the boat and in the house. And I've read enough about 5200 to be wary of it.
For posterity and my curiosity, what's the one Monty/Sage silicon exception?
