Re: Genoa Chain Plate bolts Leaking in aft hanging closet

Matt Salatino

I apologize for not jumping into this fray.
My experience with sealing chainplates with 5200 were less than good. It s difficult to find things that adhere well to stainless steel. The native oxide prevents good adhesion.
After much research, I found a GE silicone product that actually had adhesion to stainless steel, printed on its applications. After using this, 6 years later, no leaks.

I realize that we all use what we have available or can get when we are in remote areas, but, 5200? I am guessing if it seals the leak you have, you'll never get the chainplate off, and if it does not stop the leak, you will never get the chainplate off without taking some of the hull with it.

I hope that this seals the leak for you,
