I have a 15 year old PT deck. I put the crapy Olympic cedar colored deck stain on it about 8 years ago. Looks good for a minute. What would be your recommendations for a longer lasting, but does not have to look fantastic from day one? I am thinking about a Cabots solid stain called Deck Correct. Rustoleum has RockSolid product that has varying thickness. Has anyone used one of these products?
