They sell a paint for automotive interiors, but I'm not sure that would work well on a steering wheel unless you protected it with a cover. But it seems a cover would defeat the purpose.....sorry yes the tumbler,ya after i took it out and tried it in my hand it doesnt spring back.i figured being i took the steering wheel off,it would be a good time to restore it.iam getting the inner metal part to clean up ,but the leather part of the steering wheel isnt as black as it once was.what could i use to darken it up again.its not bad but noticable.thanks
