Not familiar with it either. In New Jersey.
So already commercialized? Not much of a step to manufacturing I should think.
Before 1990 there was a spray metal product called Eutectic (sp) but it was not a cold applied material though it was not very high temperature. Supposed to have been developed about 1906.
I’d call it;
“Rattle Can or
Spray Paint.”
I have utilized hot spray metal processes since 1968. Works well if the parameters are followed.
