Depends on the look you want. Everyone has their own way of doing them. If its factory new, I like the gel stain followed by an exterior clear. You could also use Sikkens Door & Window. Its a bit more limited in color choice, but probably the simplest way to get a good result with the least amount of technical difficulty.
