Is it common practice or a good idea to seal outboard mounting bolt holes and thru-hull fittings with something like resin or Gluvit before installing and siliconing? seems like it would be a good idea but this newbie knows it's better to ask first.
The 5200 is made by 3M and is good below and above the water line. It comes in a squeeze tube or in a caulking gun tube. Don't use silicone it does not adhere well and eventually will let water in.
Make sure that the epoxy is dry before using the 3M 5200 .
I guess I was talking more about using a hard resin type product (and letting it fully cure) before adding the softer bolt sealant (5200, 4200) and hardware. My thought was if you used a product like Gluvit to seal the actual wood then if water does make it's way into the bolt hole then at least the water can't be absorbed into the wood.
