I chose Trinova because I liked their wheel shine (vs Meguiar and Car Guys). This was my first time doing leather so am by no means knowledgeable, still learning but am happy with results. I think the seats are actually somehow blacker or darker than new, strange coming from a clear oil . . .
We took the family on a road trip today and most everything got dirty again . . . At least the leathers are protected for a few months. But it all looked sharp between 11pm Saturday night to 9am Sunday, really it did - just can't win . . . .
I'll post this in the Detailing thread also.
