Coil Coating, for the result to be effective?
The more coverage, the better the result will be. However, the Cooling Coil Coating helps expand protection beyond the area originally sprayed, by “fanning out” as it cures. This fanning out is similar to the way that frost spreads outward in a crystal lattice as it freezes on a window pane. This creates an additional zone of inhibition that extends out from the edges of the areas actually covered by Air Cooling Coil Coating.
