I used to use all sorts of waxes back in the day.
The best results turned out to be a Dri Wash product.
I'm always amazed that between the checking cracks and rock chips the car looks pretty shiny.
The front end has numerous rock chips from miles of fun and even a couple of marks from distinguished cone mishaps on the slalom course. These are badges of time.
This paint has NO clear coat, NO coatings and NO wax. Just clean lacquer paint.
Thanx for looking
