I've got a set of seats from a 91 GTA that are grey leather going in my 1990 formula but they need a little restoration. They don't have and tears or rips but they have some areas that are cracking that need fixing. I've heard that some guys use a compound you rub in and it fills in the cracks and supposedly makes the seats look much better. Problem is I have zero experience with this sort of thing and I have no idea what to buy. Can you guys help me out here? Thanks.

 

IMO unless you plan to never sit in the seats, any type of "fix" like this is going to be a temporary one. We usually just get aerosol seat dye for cars here at work, and they look fine until they sell and start getting used regularly.
