And if you live somewhere with nonstop blazing sun and 100+ temperatures (like here in AZ), be sure to strip the wax, do a good clay bar treatment, wash the car, then go for the formula 2001 polish.
I know, it seems too cheap to work that well, but believe me, I have found nothing that protects better.
It seems like wax is almost worthless in temperatures above 80 degrees.
