I was so impressed with the product I had to share.
White Diamond Metal Polish and Sealant
I have a lot of experience metal polishing (tripoli, rouge). I've used Wenol often.
When I first saw White Diamond, I thought no-way. It's from "as seen on TV". Its' consistency is almost water. On the store shelf it separates and top half looks clear like water.
It made my polished Centerlines gleam with brilliance. It didn't take much rubbing. Gleam like I've seen no other polish do - machine or by hand.
My valve covers are more porous. It still made them look good. It might take a few more rotations for perfection.
We'll worth the money ($14.99), and Advance Auto sells it.
