So as my stack of polaroids grow, I'm wondering what to do with them all. Once I have them scanned, I'm planning on covering a wall in one of my rooms with the polaroids. Since the room will be getting direct sunlight during most of the day, I'm wondering what is the best way to protect the polaroids to preserve them for the long run?

Are there special coatings that I can use? Most of my polaroids are "coaterless" I believe, so they do not need to be coated.

Suggestions welcome!
