Have any of you tried applying DG 101 or 105 with KSG on top? I was planning on doing my car this weekend, the usual wash, clay, possible some Sonus Paintwork Cleanser (if not using DG 101). Was wondering what the results would be, durability and looks. Am I better off just going with one system 101 + 105 or KAIO + KSG? If it makes a difference, the car is an Audi A4 Avant with Dolphin Grey Metallic Paint.
