Hi, I received a touch up set from Lexus contain a basecoat and clearcoat. But the guide is 16 small pictures with no text and help and I am not sure how to use it. As I searched others said that the basecoat and clearcoat should be shaken before use whereas on the guide it is banned. Anyone has any experience of using it? I attached the photo here. I am more confused about the step 7 and 16. In step 7, it wont scratch the car more?
