I used Wenol polish in the red tube...it's a pink product. It has a very fine grit in it to cut, use it with a buff wheel or by hand...then follow up with the Wenol in the blue tube, thats a white paste, it brings it up to a mirror shine. Works for me! I use wenol products on all my metal needs from my Corvette wheels to boat valve covers to a Dellorto Side Draft carb on my Harley .
