Specific Marine Applications for Boatlife Silicone Rubber: Ports, windshields, cleats, chocks, thru hull fittings. Recommended for above waterline use. It adheres permanently to most marine construction materials and bonds to itself.
SURFACE PREPARATION: The surface must be dry and free from grease, oil and other contaminants. Cut back any weathered surfaces and dry rot by routing, sanding, or sawing to solid wood.

2012-05-16DAVID LOCHNER: Check the manufacturer's specs. I don't think that silicone is a good choice for below the waterline applications. Try Lifecaulk instead.

2012-01-10HAROLD MONTGOMERY: Dave,
I bought this product in 2008 and haven't even the recollection on why I needed it. I'm sorry, but I have no idea if it would or would not work under water.
2012-01-03PAT KELLEY asked: can i use this to patch a 500 gal. water hauler that has a 2 inch crack in the bottom?

2012-01-12COASTAL WOODWORKS: I found the product was excellent for my purpose. Whether it is what you should use for your rather demanding application, I couldn't say. It was the best silicone I have ever used, so if a good silicone will do your job, try it.

I used this silicone to bed two sets of oarlocks, a pair of chocks, and a cleat on my 17 ft. strip-built Whitehall pulling boat. I needed a bedding compound that would absorb the constant jarring of the oars in the oarlocks and this silicone worked very well. It holds the bronze to the wood and absorbs the shock of the oar movement well.
