OK, Thanks to all who replied. I tried Adams Car Care Products and their V R T (Vinyl, Rubber & Tire Dressing) worked wonderful on my Model A steering wheel it gave it a dull luster and looks great ,seems to have sealed it up quite well ,no black hands so far.What is the best product to preserve a Model A steering wheel. My wheel is in very good shape,I heard using automobile wax occasionally would help. Any comments appreciated.
