Anybody have any suggestions on how to preserve/protect/clean the leather seats in our GPs? I just installed a slightly used, like new 40th Anniversary leather interior into my 02 GP and the "GP 40th Anniversary" that is embroidered into the seats is a lil dirty. Also, there's a few cracks here and there, I guess it's unavoidable with a leather interior ( this is the first one I've ever had so I wouldn't know...) but I would like to aviod/prevent any further cracking or eyesores to the seat. Any ideas guys? Thanks!
