Great for cleaning oxidation off of metal car trim

I received this compound with the Dremel Cleaning and Polishing kit. I used this along with the Bristle Brush bit to remove heavy oxidation off of the metal trim on my 10 year old Volkswagen. It works great! I tried numerous other metal polishers from the big box and auto parts stores and even some household remedies like vinegar, lemon juice and baking soda. Nothing cleaned it like new compared to this compound! While it is a bit messy when polishing at high speeds it is well worth the couple of minutes of clean up time for such amazing results!

Works so well!!

[This review was collected as part of a promotion.] I was not sure how to use this when I bought my first Dremel so I didn't utilize it for longer than I care to admit. Once I had a friend teach me how to properly use it, I have been more than happy with the results.
