If you want to know how to repair leather car seats, the internet is probably the best source of information for you. In my several years of existence in this planet, I have only encountered a few people who are knowledgeable about proper leather care and repair. I believe that the same is the experience of most people. Leather specialists have their own websites and getting into them is the best way that a person can do to find good results. So other than asking your grandpa or your next door neighbor, internet research is one good thing that one can do.
