    Comments about Thompson's 1 Gallon Clear Waterseal Waterproofer Plus Wood Protector (41801):

    Will make a weathered pine deck look better than new when applied properly. Apply ONE (1) THIN coat. More is not better. I used a "sealant brush" to apply. This method takes longer but allows you to brush out the product. If you happen to apply it too thick go over the surface with an absorbant rag to wipe up excess. The instructions make no reference to shaking the can prior to use but it is important that you do. Important ingredients WILL SETTLE to the bottom of the can. Shake the can well.
