No. Porcelain is a glass that is fired onto the surface at temperatures around 1600 degrees. The porcelain finish is hard and resistant to scratches. Resurfacing on the other hand, is the application of an acrylic polyurethane onto the existing surface and does not require extreme temperatures to cure onto the surface. While the new finish may not be as hard as the original porcelain, it is extremely durable. The expected life of a newly refinished fixture is 15 to 20 years.
