I have posted on this subject in the past and received some suggestions.
Truth is, I have tried several cold blue methods and all of them were worthless.
They don't cover well and hold up even worse.
Tool Black, Prema Blue, and a coupla' other private label products that were a waste of money.
Does anyone know something that truly works?
