My two cents on the Mother's aluminum polish referenced earlier:
I sand and polish progressively- finishing with jeweler's rouge on a loose sewn soft cotton wheel. Result is always a flawless raw aluminum shine. So then I tried the Mother's polish as it is supposed to shine and protect. I was really interested in the "protect" part.
So after using the Mother's on one of my case covers, it was very apparent that it actually
dulled what was previously a flawless shine
. Keep in mind that this is when sitting right next to another part that was also polished to compare it to. ( I assume the Mother's is a more aggressive polish so it can be used on billet parts and wheels with the power ball. The before and afters of that application can be amazing )
I have found that Autosol is a better final polish and leaves a protectant.......
