I've been using this stuff to recoat, done three tubes with this can and it still feels nearly full.
Unlike Slip Plate. it makes a hard black coating that doesn't easily mar or rub off on your fingers.
It's quite conductive too, I measured the resistance from one side of a 14" tube to the other and it was about 2k.
You can get it on Amazon for about $16 if you have Amazon Prime.\
