An old friend of mine just got divorced. One of her gripes about her ex was he didn't care about their cars. So she asked me to show her how to wash a car without damaging the finish.
I bought her two buckets, two grit guards, soap, MF towels, and a few waffle towels.
She learned on her old car. And she now has a solid base on how to keep from damaging the finish on her new car. She will be taking deliver on a new Audi in a few weeks. Her first brand new car ever. I did clay her old car for her, but did not do any correcion.
When it comes to correction I will be doing that for her. And I will let her make the decision on waxing VS CQuartz. I also gave her one of the little cans of Fuzion at Christmas so she can see if she can handle waxing.
And since I know someone will ask. The soap was Optimum Car Wash.
