The Mrs. wants the the front entry done in cedar shake siding, on the north west end of house. You can see the overhang so it is somewhat protected. What should, can I use to protect the bottom 12" or so, more concerned about the snow swirling in this area during winter, as opposed to worrying about rain in the summer/spring. Thoughts?

With the protective overhang and being a vertical surface, I'd probably choose a deck stain....maybe. It's going to change the appearance of the shakes so if you only do the bottom 12" or so it will be obvious. As for which deck stain, I have so little experience with them anything I suggest is questionable. I recently looked at the Consumer Reports for their best choice only to find it's not available in my state.

I would use something oil based and thin it down like wipe on poly.  Being thin it would soak in deep instead of laying on the surface.  Keep brushing on coats until it doesn't soak in anymore.  Do the backs the same.

You could also consider something like the protective coating for boat decks.  It will make it a bit darker, but will preserve.  And I suppose it will need to be re-applied every few years.  

Used Thompson water seal on the shakes, soaked up all sides of the shakes. She's happier than a jackas- eating thistle. As mentioned before, it's all covered by the overhang of the roof, and she does want it to "age" somewhat. Next question, any idea on what to do to cover the small gap to the top left of the door, to keep bugs etc out. I was thinking spray foam in a can to seal it, and getting a small false security camera to hang up there to hide the imperfections.

Looks great. For that hole in the corner, maybe you could cut and glue a piece of styrafoam insulation in to plug the hole, then finish with a bit of paint. Someone else may have a more professional recommendation but I believe a full plug in the hole will deter any insects from nesting there.

Great looking entryway.  

 

It's extra work, but you could strip off the shingles between the door and the corner, and add another corner board to make the corner L shaped.
