Hi Jerry
 I could be wrong but your mirror looks over corrected.
I believe that the wWw stroke is a porabolizing stroke. You should be using
an even W or a V stroke. You need to be working the middle zones.
 Any other opinions? I'm still learning the polishing methods
myself but this is my understanding. Dwight
