I don't normally write reviews, but this product is an exception and I wanted to at least let others know of my experience. I have a large cedar deck and every year I would have to spend 2 weeks stripping, brightening, and then staining the deck. Not much fun. It's like spending your vacation time taking care of the deck. It was an incredible amount of work and time, and to be honest... I'm just getting too old for this. So I began to research for a better product, and after MUCH research, I found Defy. Actually, what I found was a DIY who had tested multiple products on his dock and then left the wood to the elements for a year. In the end the winner was....DEFY. So I decided to try it. What I like is that once I did a final stripping of the deck, I never have to strip again! This is the third year I have applied the product, and I just simply power wash the deck and then paint on the Defy. We do have some harsh winters here in Washington, and combined with the marine air there can be a lot of breakdown in a deck finish. Defy lasts the entire year, then I merely paint it on and I'm good for another 365 days. It's so worth the money, especially considering the time and effort it saves me. I highly recommend this product and I have already recommended this to my friends with cedar decks!
