Hey back in the early 80's. Yes I'm old we use to use cornstrach as a final polish to make the car really shine. So putting ice water between carnauba wax seem logical to cure it.
All the supplies we used came about from using different stuff to make the shine better

Ha. I was wondering when someone would mention cornstarch. We use to use it all the time when removing carnauba. Harly wax then dust with cornstarch. Sometimes these little tricks get lost over time.
