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! Todd M-23 #86
You can use Life Caulk. Made for above waterline and it's removeable. -----Original Message----- From: todd@btbuilders.net To: 'For and about Montgomery Sailboats' <montgomery_boats@mailman.xmission.com> Sent: Tue, Sep 17, 2013 3:31 pm Subject: M_Boats: Sealants for re-bedding deck items Hi All - I will be re-bedding my teak handrails ect.

You can look up the 3M 4200 and 5200, there's tons of info from 3M and others. They are both called "adhesive sealant" by the manufacturer, meaning they adhere things together as well as seal them. I have heard 4200 called more of a sealant and not so hard to remove while the 5200 is definitely adhesive as well as sealant and very hard to get off of anything it gets on. So the 4200 is more "removable" - that being a relative term! cheers, John S. On 09/17/2013 08:26 PM, Sandy 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: http://www.pbase.com/mainecruising/rebedding_hardware&page=1 Tyler On Sep 17, 2013, at 7:09 PM, Todd Bradley wrote:

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:

Hi Todd, I am in the process of rebedding all my deck hardware and teak. Found a website that sells butyl tape. It is a marine bedding compound that stays fexible for decades so it will flex and not crack and allow water to infiltrate your deck via the fastener holes. When you do want to remove the fitting you slowly pry it up and cut the butyl with a knife. The website is really informative as to what makes a good marine bedding compound, worth a read. www.pbase.com/marine cruising/butyl_tape I just received two rolls of the product and it looks and feels like it will go a good job.

There is a difference between the butyl tape you can get at RV stores and top line marine butyl tape. I bought some of the good stuff from Compass Marine (http://www.pbase.com/mainecruising/boat_projects). This is also a good website for how-to articles. The only thing I don't like about the stuff is it's tendency to "creep" out from under the sides of the fitting for days and even weeks as it slowly compresses. The seal is still good and I'm sure it will last for many years, but you will have to trim this excess off more than once to have a clean installation. Even then, the edge of the butyl tape that is exposed remains sticky and will collect dirt and small debris.

Yes it does creep a bit. Still scraping along my traveller track. The seal is very good, so it is a small price to pay. Bill On 2013-09-18, at 11:04 AM, Larry Yake <larryyake@gmail.com> wrote:
