The clapboards are western Red Cedar. I put then on backwards so that the rough side was out to the weather and just use a natural/clear oil stain on them, which is getting harder to find where I am. The last time I used Super Deck Natural #1910. They are 20 years old and have darkened some what. The soffits are just eastern white pine tongue and groove boards I bought at local saw mill I use. Wife and father put a red wood/sequoia stain on them before they went up and I haven't touched them since.
