My 99 SE Maxima sits in the sun alot and because of it (and alot of wear), the leather on my drivers seat (that is tan) is starting to turn "grayish" and show the wear? Can you refinish or add some color back to some well used leather?

 

Are you sure it's not just dirty? Try using Mr. Clean Magic Eraser Bars. They worked wonders on my tan leather. It looks brand new! They weren't worn though, just dirty.
