SEAL-ONCE® Premium Waterproofing Wood Sealer & Stain is designed to protect & stabilize marine wood against water damage, salt water spray & decay.  Unlike many top-coat sealers on the market today, it penetrates wood below the surface, coating the wood fibers at the cellular level, which creates a long-lasting, flexible, breathable barrier.  It provides long-lasting protection from the inside out.
