I would recommendone light coat of Perma Chink Interior stain, Light Honey color, with a coat of either Gloss or Satin Acrylic clear over it. It will still have the natural color for the most part. You may just want to put a couple of good coats of the clear. You can do that on the interior since the weather is not an issue. I would recommend putting some extra UV blocking agent in it to help stop fading around wall hangings. DO NOT use Poly.
