A water resistant porcelain enamel coating and method of making the same is provided. The porcelain enamel coating is prepared using a ground glass, preferably a borosilicate glass frit, and mill additions of silica or silicon carbide and a zirconia compound. The mixture is applied to a metal substrate and fired, resulting in a water resistant coating that resists cracking and crazing. The coating is particularly useful in water heaters.
