Hello everyone. I have searched for hours trying to find the answer but i keep getting "in general" answers such as "as long as the shampoo doesnt have wax. I thought i would post this before i make a purchase. I use Zaino on my Vette and i am out of shampoo. I would like to try other products such as DP Auto Bath or Pinnacle Bodywork Shampoo. The question is are these products safe to use with Zaino? Thank you in advance for you suggestions.
