one word of advice, if your making motorcycle seats, you don't want to dye your seats black. It rubs off and your customer will be walking around with a black butt. They won't be happy! There is NOTHING that will prevent the rub off, trust me on this one guys, lots of guys say they can prevent it with satin sheen, or super sheen. Well as soon as that sheen rubs off the black will rub off also. AVOID BLACK DYE.
Any black seats that I do I use factory dyed black leather with no tooling.....
