Caulk For Mounting Bolts For Swim Platform

Postby bmat5 » Fri Jun 11, 2021 10:11 pm

After completing some maintenance, I need to re-attach the swim platform to my 2005 170 Montauk. The swim platform was originally attached with bolts and sealant. At least one bolt is below the waterline.

Q1: What sealant should I use?

Q2: Among 3M4200, 3M5200, or Boat Life Calk, which sealant should I use?

I would use Boat Life Caulk.
