I have used Wheel Wax, and others, in the past and did not see a difference with it. I was highly suspect any type of wheel wax being able to stand up to the heat, especially on the fronts, and I remain convinced they can't.

I have used Zaino Z6 on my wheels just to make them shine a little better and it does do that. But like I said, I am sure as soon as I hit the brakes a few times and the heat builds, any protective properties from the Z6 disappear.

No experience with Pledge.
