[Don Metznik]

Aside from approaching the task with 2 people and considerable patience, what special advice would you offer regarding re-bedding the lifeline stanchions? What is the best material to use? Thanks.

Try using a very large screwdriver above decks and a good wrench below. You will need a helper to do it easily. When rebedding, try using 3M 5200 sealant and adhesive. Use plenty of it so that it squirts out between the deck and the stanchion base. You can clean the excess off later.

Don,

Clean the 5200 residue off with isopropyl alcohol. It works great, and is cheap! Note: If you ever want to remove the stantions in the future you will have to cut the 5200 to get them off!

Don,

First, I would recommend that 5200 *not* be used for the very reason that it is so good at what it does..it's permanent! Lifeline stanchions get loose occasionally..from a variety of reasons, and they will need rebedding or retightening. This will mean cutting the stanchion free from the deck..plan on a whole Saturday shot here.
Better to use Lifecaulk on it, and have the ability to repair what ever goes bad in the future.

My stanchions have an "O" ring inthe base to act as the sealing part. Normally these would be all that is necessary. But if the darn thing does not seem to seal up, try replacing the O-Ring first. Then if needed, go the bedding route.

You never want to make something impossible to repair in good time. It just causes troubles for you or the next owner down the line, and frankly, 5200 is not that good of a sealant anyway ( I used it on my seahood, and now have dried and splitting caulking that won't come out easily -lesson learned!).

Good Luck!

I've been told that 5200 cracks when exposed to UV for a long period. It's not supposed to be good for bedding hardware to a deck. Life Caulk or equivalent is supposed to be the stuff to use.

3M 5200 is not designed for servicable hardware bedding, period! People miss use it all the time. It is designed as a *construction sealant/adhesive* (polyurethane based) for such uses as bedding a hull deck joint or installing a shaft support strut or bedding a keel or a stem fitting. Never use the stuff on stanchions or any other deck hardware. U.V. rays from sunlight ruin 5200, it turns yellow, dries out and cracks. Deck hardware should be bedded in polysulfide such as Lifecaulk as an example or 3M 4200, there are other brands of polysulfide as well. Other less effective beddings are silicone, acryl/silicone, and others, even natural bedding compounds.
