I have been using stuff from Griot's Garage. Really high quality (and priced accordingly). Used to show my Jaguar S-Type R in shows and routinely won awards and used nothing but Griots.
A few years ago, I traded in our 2005 Jeep Grand Cherokee with 70k miles, and the guys made me produce the registration to prove it was 7 years old!! Looked like brand new.
Several major car museums (including LeMay here in Tacoma) use their stuff as do a bunch of high end car dealers in the area (Bentley, Ferrari, etc.). My 2011 Saab 9-5 just turned 50k this summer and even after a 5k summer trip still looks like new. Hoping to do my Fall cleanup in the next couple of weeks.
