Re: Best wax for black paint?
Since I personally hate repetitious "drudge" work, but also love a shiny car, I long ago developed my own procedure.
Porter Cable makes an excellent orbital buffer, their model 7424. Using it and a foam pad, I can quickly wax any car with NO swirl marks. If I am redoing a heavily oxidized car, I will use my Makita rotary polisher with a 8" wool pad, then finish with the Porter Cable. Got the Porter Cable idea after watching the local detail shop guys using one.
I've found the machine makes more difference than any of the waxes I've used, including the Zymol, Meguiars, Mothers etc. I did do one test - Using side to side comparisons (each side of the car with a different product) Rain Dance beads water the longest.
