Best Wax for Clearcoat Paint

My 71 Dart Still Is The Original Paint And Mothers Works The Best For Me. The Others Leave Streaks Or Uneven Looking Areas.
I Use A Clay Bar About 3 Times A Year Before Waxing.
I Use Mothers Wax Not Cleaner Wax.
My dart is a daily driven car and a show winner at car shows.
70,000 miles /6 auto, tawnny gold paint(looks green) that is parked outside all the time.
