Bedding Compound? Sealant? Which Fittings?
 

I am a little confused about which pieces should be installed in a "bedding compound," which should be caulked in with sealant, and which don't need either. Also, what exactly should be used for "bedding?"

cleats (pull-up style): bedding?
bow light (pull-up style): bedding?
thruhulls: sealant (4200)
rodholders: bedding? gasket?
fuel fill: bedding?
louver vents: nothing?
misc. rails, ss/alum accessories: nothing? bedding?
hinges/pulls on hatches: bedding? nothing?
everything else???

I'm sure a lot of it probably doesn't matter, but would love to know the right way to do it, or least what the guys with more experience think...Thanks.

On my boat anything below the water line gets Life-Caulk,
any thing above gets Life-Seal.
Any time you put a fastener through fiberglass there is an opening for water intrusion.
Good luck with your project.

sealing the core,as certain equipment is installed is a very important step,most owners skip-rod holders installed in the cover boards,these are an excellent example-the hole for the holder goes through a cored surface-the cored surface,be it either wood,or composite,needs to be properly sealed,to prevent water intrusion-polyester based resin,is a poor choice for this-epoxy ,being waterproof,is a much better choice...

as for me,deck hardware,thruhulls,etc,3m 5200-there's a common mistake made by the inexperienced,3m 5200 is permanent,untrue ! over the years,i've installed numerous equipment on customer's boats,bedded in 3m 5200-in the case of a few,the equipment was removed,without damage to both the boat,and the equipment.i've removed many transducers,bedded in 3m 5200,gunnel caps,rod holders,etc...

here's some more information on this very subject,it's one of my facebook pages...
