Coal tar enamel provides an extremely long service life, under the right conditions. The Bureau of Reclamation (Reclamation) has observed more than 80 years of corrosion protection at facilities such as Hoover Dam. The coal tar enamel linings in penstocks and outlet works that are buried, encased, or in tunnels maintain excellent condition with minor damage. However, when temperature fluctuates between hot and cold, the enamel is stressed and develops alligator cracking.
