The coating appearance was uniform in color, with no indications of degradation (blistering, peeling, flaking, cracking or separation of coating from the metal surface). The coating outerwrap appeared to be evenly applied, with the edges of overlapping layers of the wrap sealed with the coal tar enamel. Further, there was no discoloration or evidence of corrosion product under or at the edges of the wrap, and the coating surface was solid to the touch. Photos are attached.
