Some of you may have wondered why all aircraft windows and so many other parts in the pictures I showed in previous blog posts about The Boneyard are covered with white paint?

C-130 Hercules covered with spraylat (note that it is fitted with skis for Arctic and Antarctic operations).
To protect heat-sensitive parts from the desert high temperatures these parts are covered with two different coatings: the first layer being a dark paint while the second layer is the characteristic white one, reflecting sunlight and heat. The paint is a vinyl plastic called spraylat after the company that produces it, Spraylat Corporation.
You may check the detail of Aerospace Maintenance and Regeneration Group (AMARG) storage processes in the following two links from the Wikipedia and “AMARC experience” (“AMARC” being the previous name for AMARG).
