Don Casey does a great job explaining what to do to remove the stanchions, remove the bad core spots, reinforce the area around the base of the stanchions, rebed them and remount them, meanwhile removing any soft core materials you may have around the old holes where the leak may have gotten in through the holes.
Check out <i>Don Casey's Complete Illustrated Sailboat Maintenance Manual</i> for a great "how to". I got a hardcover copy used for $33. It is worth every cent. West Marine also does a great job describing how to do it too.
I don't recommend using 5200 when rebedding your stanchions, simply because you occasionally have to rebed them, and 5200 is designed for adhering something for good (like the keel to hull joint). 4200 is a better choice since it's somewhat easier to remove.
I second the recommendation for Don Casey's books, well worth every penny I've spent on them. He'll also have a recommendation for what to seal your stanchions with, I think he recommends polysufide, but I'm not sure.
I search through Half Price Books for Casey titles every time I go, and just buy whatever I might find, I know I'll eventually use it, and at least read it. Pretty much the same for Nigel Calder books.
The ONLY place on a boat 5200 should be used is the hull to deck joint. Almost the same for 4200. Use a sealant, NOT an adhesive to rebed your stanchions. Why they continue to distribute 5200 to gullible sailors is beyond me.
On Dave B's advice, I am now a firm believer in Polysulfide.
Last winter when I refinished all the teak on Passage, this was the first time I'd worked with it. What impressed me was that after years and years in the elements, heat and cold, the old polysulfide still remained flexible and removeable. It took a bit of elbow grease, but lo, it could be completely removed.
On reapplication, I was worried about using it to rebed the teak, and again, if you manage it, you can prevent it smearing or dripping and getting all over everything.
And, in the few cases where it "got away from me", I waited a week or so, and I was able to rub and peel it off straightaway. No muss, no fuss. I am a convert.
I could not imagine using an adhesive to bed anything that I ever wanted to remove in the future. I'd imagine some dynamite would do it, but short of that I would not use 5200 on anything that I did not consider permanent.
