I'm polishing a set of Zq8 wheels, and are almost finished. But, on the final polishing step. I seem to be getting some shadowing or ghosting affects. In the polishing manual from the website, it states to use corn starch or talcom powder. That isn't working. I've heard that it's caused from heat. How do I get rid of these spots? This is my third time polishing aluminum and have never experienced this before.
Suggestions.
