Black leather, polish?

[Guelphguy]

Wondering, on a black leather interior, it is not torn at all but where the seat belt rubs on the bolster there is "white" cracks, can this be simply touched up by using like a black shoe polish? Any other tips, the interior is in awesome shape aside from just this one drivers side bolster.

or scuff dye then rub some polish, and rub some more with a white cloth

keep rubbing or you'd better be wearing a dark suit for the next week or so
