We've had some good comments regrding epoxy coating lately, and I don't want to jump into a particular thread and steal any thunder from an ongoing conversation, per se, but I do want to address the concept of epoxy coating in general. First of all here are a couple good (recent) comments people have made about epoxy coatings, and there are many more too.
Chris Craft to my knowledge did not find a need to use epoxy coatings on any boat I've had, at least I have not found it yet if it is there.
My 1968 35' Sea Skiff was near the end of their hallowed wood boat production era, and it had no epoxy anywhere. Normally I would see something like a wood bulkhead sealed with either varnish or bilge coat, and that allowed the wood to breathe if it got wet.
VERY IMPORTANTANTLY: Epoxy should never but never be used as a crutch to make inferior wood work on a marine environment, such as making non-marine plywood last longer. I think it is a waste of time, personally, and I would recommend anyone doing any work on a boat use marine plywood (and forget the epoxy on most applications). If the bottom of a Chris Craft Sea Skiff was 1/2" of marine plywood, with paint on the bottom and primer on the inside, why would something in a cabin need to be covered with epoxy?
I know I'm wrong on some of this stuff, but I wanted to share these thoughts to get people thinking about it. My fear is that encapsulation will trap moisture, especially on inferior wood, and this will accelerate the damage. For something like swim platforms yes epoxy may well be the answer.
Comments please !
