Stop in for a cup of coffee
For polishing, any good brand will do. I like the Mother’s or Meguirer’s. For synthetic wax, either Zaino or Turtle wax ice. Other synthetic brands may be good also.
I avoid carnuba since it is just a natural wax that contains water soluble fatty acids and doesn’t last as long as synthetic against water or washing....by less than half the time. A good soap can nearly strip carnuba off completely in just one wash.
