WAKSOL - a waste of time and money

Used Waksol on my hardwood deck and noticed that it washed off when it got wet. So I gave it another coat. Same result. Foolishly I gave it another coat and for a while it looked OK. Recently it rained for an extended period and now the deck looks terrible. Patchy and you can even see where the drops dried. Don't waste your time and money on this ******* product. No mention on the label not to use on hard woods.
