Clear Coat™ and SilverTip™ Epoxy offer excellent barriers to both liquid and moisture vapor. They are easy to apply with a brush or a roller, and will cure to a tough, clear, high-gloss film, which will waterproof the wood.
SilverTip Epoxy is a crystal clear, blush-free epoxy system. SilverTip Epoxy is an excellent choice for brightwork applications due to its brilliant clarity and rapid film build characteristics. Due to its low viscosity, SilverTip wets out a variety of reinforcement materials with ease. SilverTip has a high modulus and develops rigidity without brittleness. The cured film is tough and resilient, with good heat resistance.

Durable Outdoor Finish? - The Wood Whisperer
System ThreeS-1 is a two-part clear, penetrating, waterproof, epoxy sealer. It is completely waterproof and suitable for use above and below the waterline. If you are doing any kind of outdoor project or build - boat or Adirondack chair, sealing the wood prior to assembly or even after means the wood will move less and water will be less likely to get underneath the finish, which will prevent mold and mildew from growing and destroying your finish and wood.
