--no-- you do not heat this to a color---take a ox--acet. torch and just warm it up --a wipe with wet rag and paste floor wax-- multiple applications are usually always needed--just work with it for a while and you will figure it out---believe me it ''ain't rocket science''-- it's really important to get the metal clean before you heat it up--i found a wire wheel on a grinder works the best for me. gotta get all scale off metal for best final results--give it a try and have fun
thanks for watchin and get back and tell us how it worked for u. re steve
