on a scale of 1-10 black T is about a 6 in my book
if i am not mistaken this used to be called EXO or EVO cant remember exactly. It was used alot in turbine coatings, impellers, high speed gears etc extreme enviroments. I wanna say it was used in pipes that was used for transporting liquid sodium(nasty nasty stuff). For some reason i wanns say race boats have props coated in this stuff to.. i could be mistaken on that.
Im gonna go out on a limb and say this coating is higher than a cats meow. I would like to know some details on this stuff
