Well, I ended up using 5200. I bought some Sikaflex 295 (which is supposed to be like 4200) to do the job, as I could not find 4200 or Butyl Tape for sale anywhere in Krabi Thailand. But, after I pulled the chainplate off, with the help of a friend, found that the new batch of SikaFlex had already gone off. So, my friend helper, who has owned a boat for 40 years said WHY ARE YOU USING SIKAFLEX anyway... That stuff is crap!
Then he said a few things like -
When was the last time you had the chainplate off?.... I answered - Well, never!
So, when's the next time you are going to take it off?... I answered - Hopefully never!
Sounds like you need to use 5200, and I'll tell you another thing... There is no way you're not going to be able to get the chainplate off if you need to...
I had some 5200 in my fridge, so I pulled it out, and sealed it up.... After making a huge mess. The job was done.... It was a pretty easy job, including removing and replacing the Rub Rail, it took about 3 hours. The hardest job was cleaning up the extra 5200.
