[quote=jonathan162][quote=shortyfox]Dana, it will take years for that to become a problem. If you're still concerned, bedding it with silicon should do the trick.[/quote]
Excellent idea, except for the "bedding it with silicon" part. The theory is good, but the problem is that while there are lots of great silicone RTVs out there, [i]none[/i] of them are the domestic/household bathtub stuff. It's worse than worthless around boats - it sticks enough to make cleaning it off a giant PITA, but not well enough to actually seal anything. For many years I've used nothing but Sikaflex on boats, but have recently been introduced (by Tom Haberman) to 3M 5200, and it looks like pretty amazing stuff (if you're not in a hurry, because it has a loooooooooooong cure time). I do a lot of work on cars, and find the specialty RTVs like Permatex Ultra Grey and Ultra Black to be excellent in their specific applications, but would have to experiment with them in marine application before formulating an opinion.<!-- editby --><em>Edited by jonathan162 on Jun 21, 2021 - 01:06 AM.</em><!-- end editby --> [/quote]
