I'll have to try that on my grille, if I can find a big enough tub! On the anodized "Custom" side moldings from my 64 Suburban, I knocked off the anodized coating with a wire brush in a die grinder, and some 150 grit paper. I then progressed through grits until I got the shine back. I've polished them once so far since last winter, and with no coating, they've held up well. Look like chrome!
