Thanks to all here for their advise and thoughts.
Clarification on the pics, they are the day after the deck was built and before any sealer was applied.
The "contractor" pressure washed and the applied Cabot semi transparrent cedar stain to the deck top and sides, not underneath. The framing is treated and the rest, including the skirting and covering of the posts are cedar.
Right now, the deck looks very good, but I am meticulous in trying to keep it that way for a long time. I am convinced that sealmaxx will harm the cedar in the long run, and have opted to not put that on the deck. My wife and I really like the look of the Cabot semi clear, but I do not want to do this every year. Any thoughts????
I will give Tropical Wave a shout as well. Again, thanks for the comments....
