Should I use the Dawn detergent for the first wash, or would it be better to use the Z7 soap?

 

It depends on what you are going to to for your polish or cleaning step. If you are using ZPC, then you don't need Dawn. If you are skipping polishing and paint cleaning and just using Z-5 and/or Z2, the use a Dawn Wash first.

 

I was going to wash w/Z7, the polish with Z1 and then Z2, with MAYBE a coat of Z6 in I had streaks. Your thoughts, please?
