Marine Caulking~ Which One Do I Use??
Products highlighted in this episode:
– 4000 UV
– General Marine Silicone
~ Dow Corning
– 791 Structural Silicone
– 795 Structural Silicone
With the exception of the silicone, all the products from 3M I consider to be excellent “bedding compounds” which are what is best used for general sealing / water-proofing. Whether it’s deck hardware, thru-hulls, wood trim, etc a quality bedding compound will preserve the integrity of the boat by keeping the water out, and the core nice and dry.
All of the caulking from 3M come in white, but 5200 is also avail in black, tan and mahogany. I had mentioned that 5200 is a product that I don’t use very often on fiberglass boats, however when working on wooden boats this adhesive / sealant is a must have!
An excellent source for ordering this material is Jamestown Distributors and West Marine
The glazing compounds that I use when working with poly carbonate (aka plastics) is made by Dow Corning. This caulking is avail in almost any color you would need (12 different options) and forms a very strong bond to the plastic while providing excellent waterproofing ability.
The best source I have found for this material is from Sealant Engineering Associates
