rebedding deck hardware

[osteoderm]

For most bedding, don't discount good old-fashioned oil-based bedding compound. Keep in mind that a good bedding compound is a sealant, not a glue, and only needs to be sticky enough to stay in place. Stay away from 3M 5200!
If you just have to have something modern and gluey, I'm liking BoatLife's Life Seal; a little easier to work with and far less aggressive than most straight polyurethanes. Where bedding is exposed to the elements (such as around the trim-plates of inboard chainplates), I'm having great results with 3M UV4000; far less aggressive than the other usual 3M suspects (less likely to tear chunks out of your gelcoat when pulling hardware), and far more resistant to the checking and chalking most modern goops exhibit in the sun.
