Abstract: A coating protects a dissolvable component of a downhole tool, so that the dissolvable component can be deployed to a desired downhole location, perform under high stress for fracturing operations, and be efficiently dissolved after the fracturing operations are completed. The present invention elevates known greases for this functionality usually performed by complex factory fabricated polymer and metal coatings. The coating includes an activation layer, a first grease layer, and a second grease layer. The first grease layer and the second grease layer have differential grease layer consistency ranges and thickness rages. The coating includes non-uniform layers of manually applied greases onsite to control degradation of the component substrate as effectively as factory coatings pre-fabricated on the components.
