A solid layer forming is due to oxidation of the surface. This cooling effect is due to the surface being exposed. To prevent this, you would need to get rid of all of the air and put a layer of plastic wrap over the surface without any air under the plastic.

Why is nujol used?

What happens to zinc when it is not galvanized?
I don't think you've understood the process. Galvanizing is the name of the method by which you apply a surface layer of zinc on to steel or iron, to prevent it from rusting. Applying a surface layer of zinc onto zinc doesn't really change anything.
