This weekend I had my dad travel to alabama to pick up a 2007 Triple White Edition NBC (I was busy with school stuff) and it is in pretty immaculate condition. It has 41k on it now and has a brand new top. I did notice, however, that the leather inside the pouch of the seats have yellowed (probably due to aging and sitting in the sun which is expected). But what products can I use to make them white again or to make the seats whiter as they age? I've heard of some leather dye sprays and balms but I would like to know what you guys recommend??
