Anyone have experience with composite decking?

[forgop]

Thanks for the advice-

The house is just now 20 years old with a really nice deck (38x18) with nice bench seating in 4 different locations and a built-in deck box next to the screen-in porch. I think cedar would look really nice. I just know nothing about it and wonder how hard it'll be to keep it from graying on me.

Here are some pics-2 from today and 1 from the house listing of when it was clear (needs cleaned up a bit from spring cleaning at the moment). Like you said, if I do this, there won't be any seams in it at all this time around.
