The Brazilian Rosewood Oil in the formula deeply penetrates the wood, offering robust protection against moisture, which is crucial for maintaining the integrity of outdoor wood structures.

This sealer’s durability is one of its key strengths, as it combines oil and urethane to create a long-lasting finish. Additionally, users appreciate the ease of application, as it smoothly coats wood surfaces and provides a beautiful, transparent finish that enhances the natural look of the wood. However, a significant drawback is its shipping restrictions; it cannot be shipped to multiple states including AZ, CA, and NY, which might limit accessibility for some buyers.
