1. A method of protecting an inside surface of an e-vaping device portion from corrosion, the method comprising:
preparing a coating mixture configured to protect the inside surface from corrosion, the preparing the coating mixture including
preparing a filler mixture including a first polymer and a filler, the filler mixture having a pH smaller than or equal to 6, wherein the filler includes at least one of TiO2, clay, ZrO2, ZrO2—Y2O3, CeO2, Al2O3, or a combination thereof,
preparing a silane mixture including silane at about 5% to about 20% and having a pH which stabilizes hydrolyzed silane,
combining the filler mixture and the silane mixture in a ratio of about 6 to 1; and
coating the inside surface with a permanent protective coating based on the coating mixture;
the coating being performed via electrodeposition.
