1. A product with a protective coating, comprising:
a product body,
a first dried layer formed on a surface of the product body, wherein the first dried layer is transformable by in-situ polymerization into an inner polymer layer;
a second dried layer formed on a surface of the first dried layer, wherein the second dried layer is transformable by in-situ polymerization into an outer polymer layer;
wherein the protective coating comprises the inner polymer layer in contact with the product body and the outer polymer layer covering an outer surface of the inner polymer layer,
wherein the outer polymer layer is a fluorine-containing polymer layer formed by in-situ polymerization, and the inner polymer layer is a fluorine-free polymer layer formed by in-situ polymerization.
