How does it stand up against oils, stains, salts, and discoloration?
Because of the protective properties of the sealer coat, it is a non-porous finish. The majority of stains due to oil and grease wash off with mild detergent. Salt, deicers, fertilizers and such have no effect on it whatsoever. In addition, because of its unique UV (ultra violet) additive, it will not discolor due to exposure to sunlight, even in the harshest of conditions. It should be noted however, that periodic cleaning will help to maintain its beauty for many years to come.
