I originally posted this in the deck section, but it appears everyone there is out building decks...

I'm thinking of using a SW toner on a cedar porch I just did. It's covered and faces East, with large trees offering protection from sun. So, not a lot of UV rays, but water is still an issue on the perimeter.
They want the new look of the cedar to last as long as possible, (within reason I pointed out to them). What would be your choice? Here's two pics. I don't want to wait too long on this if weathering is an issue in your opinion.
