Educate me on proper sealants
What sealant do I use to seal exhaust tips and the fastener holes?
What sealant do I use to seal external steering brackets and fastener holes?
What sealant do I use to seal tie down U bolts and holes?
What sealant do I use to seal thru hull fittings (above the water line)?
Appreciate the time, Fellas!

I liked to use 3m 101 Marine Sealant (polysulfide) on items I may want to remove, but I guess it was discontinued by 3M. Another polysulfide sealant similar to 101 is BoatLife Life Caulk. I like 4200 too, but find the polysulfide's are a little easier to work with and also easier to remove later.

"3M 4200 Fast Cure is a one-part general purpose polyurethane sealant with good adhesion to wood, fiberglass, gelcoat, plastic, and metal. When cured, 4200 forms watertight, weather-resistant seals on joints and boat hardware above or below the waterline.
4200 FC (fast cure) is ideal for hardware and bedding applications. It is paintable and sandable. While 3M 5200 sealant results in permanent bonds, 4200 has approximately half the strength, making it a good choice for applications where the bond may need to be broken in the future such as replacing hardware."
