The polymer base of Lifeline Stain is designed to bind the stain pigments to the wood. Eventually, like all semi-transparent stains these bonds weather and weaken and the stain wears out. A coat of Lifeline Advance over the Lifeline color coat protects the Lifeline finish and will extend the life of the stain. Lifeline can be used without Lifeline Advance, but once you see a home distinguished with a coat of Lifeline Advance you understand why all the fine automobile manufacturers use a sealing clear coat over the color base coat.
