I will second the use of butyl tape. Have used it so far on rebidding the teak handrails, new deck organizers and cam cleats, new traveller rail on the cockpit floor. I am so done with 5200. Bill On 2013-09-18, at 12:32 AM, Tyler Backman <casioqv@usermail.com> wrote:
From my experience, butyl tape is easier to work with and lasts longer than any other deck sealant. It remains soft and pliable indefinitely, and doesn't make a mess. My experience is that even 4200 will start leaking after a few years in things that have some movement (like chainplates and handrails) but butyl tape will never leak when installed properly.
Here is a very good process for re-bedding that will permanently prevent core water intrusion:

Hi All -
I will be re-bedding my teak handrails ect. I have been reading about various marine sealants. According to Don Casey's book, he suggests using a Polysulfide if you ever want to get the item off again. Which I may need to do someday.
I know many of you use the 3M 5200 product which is a polyurethane. And according to the Don Casey book is extremely difficult to remove if you ever need to. In researching the sealants, 3M makes a 4200 that is supposed to be easier to get off if the someday comes. Has anyone used it?
I hope you can let me know your experiences & recommendations.
Am I over-thinking this?
Thanks!
