I have not, want me to order up some black tonight?
This
its suppose to be way stronger than paint, because its basically a plastic coating. i cant tell you exactly how strong it is because i haven’t had the heart to smash any of the stuff ive coated yet. when it comes in ill try it on an old wrench or polished socket and then smash it see the turnout. I’m curious to see how strong it really is myself!
