I'm like others here, I use a variety of different manufacturers products. I have to say though that my favorite polish and wax is einszett. I have a 2002 sliver Passat and 1Z makes it sparkle like a pool of water. They are so easy to use and I get execellent results with minimal effort. That is my priority, a great look in record time, I've got an 18-month-old now and I don't have the time or energy to devote to my car as I once did. I like Meguiars too. I've had amazing results with Medallion Premium Paint Cleaner and SMR 2.0. I think their #26 Hi-Tech Yellow Wax is great. It produces a very reflective gloss and I've had it last 2-3 months on a garaged SUV. I've also used 3M's Fine Cut Rubbing Compound to remove scratches, scuffs and marring by hand.
Good luck, finding a process of products that work for you is key. Don't get too caught up in the hype, we all have different stories to tell and it all so subjective. Try something, and if you like what you see then use it and enjoy!
