I have a '95 Vette in which the the door over the small storage compartment in the driver's side door broke. Had to order another one from a salvage yard. Just received it and it is in pretty good condition, no cracking in the leather, but the black leather over it has started to fade and turn "brown". Is there a product I can use to restore the leather to its original black color? I have researched the AutoGeek website, but don't see one that will solve this particular problem.
