In my Euro car scene days I used vinyl sprays several times on to change the color of door panels and dashboards and it always held up real well, but neither of those are high wear areas, so I can't say how they would hold up on a seat. If you're not going to be riding with a passenger much I would guess it would work great. My only concern is being able to match the black from the seat, versus what came out of the can, unless you masked those parts and if it was a different shade of black, it would be aesthetically pleasing
