I am restoring my 89 M3 and am not sure where to go with this. The PO did the wheel wells and spare tire in just some black rubber undercoating but as we know when they left the factory the underside and wells were color matched. So my question is do I leave the wells black as they are now and just re-undercoat the rest of the underside in wurth black undercoating or do I grind off all the black undercoating and redo it all in a color matched white undercoat????
