i believe im going to get the car professionally buffed using the prime werkstat. ill use the Z5 as a topcoat and apply it by hand. also going to try the zaino car wash.
Chemical Guys is the jam! I have many of their products and they are awesome, and a great value. Much better than some off the shelf products, and not much more expensive. I have their medium claybar and Luber, Scratch and Swirl remover, Green Clean, window cleaner, Liquid Leather, and their wash mitt. I just got a lot of this stuff and just recently used it this weekend, and I have nothing but great things to say.
As for topcoat, I use either Meguires Deep Crystal liquid wax (x2 coats), or Harly Wax which is a 100% pure carnuba wax from California. My dad has been using it for like 20 years and swears by it. I only use it when I'm at home and I snag a little from him
