For certain clients, we specify a "duranotic" finish on the backs of highway guide signs, which are aluminum panels. Quite honestly, I never knew what it meant either. :-D I found a brief definition here:
"Duranotic Coating: Commercial grade alternative for hard anodizing of aluminum."
While performing a search, I also found instances where the word "duranotic" had a "TM" symbol after it, but I don't know who might own the trademark...
