Wooden Deck Maintenance-Paint or Stain

I get about three good years out of my deck stain also. I use a product called CWF-UV cedar color, get it at Home Depot and it really looks great. My deck gets beat to hell with brutal sun and all the harsh elements up here in Michigan. Right now I am on my fourth year but it need,s it again. I also have two decks and a porch that I did in Trex and they look great, just need to power wash them from time to time because they get dirty, only problem with Trex is that when the sun beats down on them they get so hot you can't walk on them with out shoes or you will burn your feet.
