Deck Stain for Composite Decking

Hello All,

I am looking to find some information on deck stains that work for composite decking. When I purchased my house the deck and screened-in porch were already in place. I do not see either one of them being more than 8 years old, but it looks as if neither have had any previous work done to them. The floors and top rail of both are composite (faded) and the pickets and framing holding the pickest are pressure treated. My wife and I want to stain everything that is "wood" white in color and then go with a darker brown for the floors and top rail "composite stuff". Do you all have any suggestions as to what would be a good stain to go with for both? I have not had any luck seeing what stain is good for composite material from looking on this so, or maybe I am just not looking in the right areas. Thanks for all of the help in advance...
