I'm just about ready to start treating the floor, decking, and frame work of my rebuild and have a few questions. I'm wondering if anyone has every used the Armoral (SP) wood sealer and if you prefer it over the Thompson's water seal? Secondly, a coworker said that he hear on a fishing show several years ago to only treat the top side of the wood to allow it to breath. Would this apply to this type of sealer or only the epoxy or fiberglass resin sealers? Has anyone else every heard of this?

The boat is garage kept when not in use if that makes a difference.

Thanks in advance.

Never heard of the breathing thing on the wood.  I'd use epoxy resin to treat the wood, NOT fiberglass.  Fiberglass resin is fairly brittle when attempting to use as a standalone sealant away from matting.
