After almost ruining my rough sawn cypress siding with linseed oil and mineral spirits I tried the DEFY Extreme. The immediate results are very satisfactory. I cleaned my siding with bleach and then used the DEFY Wood Brightener before the clear stain. The product went on well with a sprayer, but needs brushing to evenly soak into the wood. The DEFY brush (similar to a car was brush) worked well and cleans up easily with soap and water. The product is very watery and milk colored out of the pail and did get on adjacent areas. I wiped the excess up as best I could, but being crystal clear if left no noticeable coloring after it dried. It beads water and yet allows the natural color of the cypress to come through... I am very happy with the results.
