sodium hydroxide...Lye...is what you want to strip the anodizing..Most local hardware stores carry the chrystalized stuff in a plastic bottle used for a heavy duty drain cleaner/opener...I made up a throw-away container out of a cardboard box and some heavy plastic...Big enough to do the 65 dodge grille and some trim...

I taped off the headlight bezels with "fine line" plastic tape for the striped areas... Worked great... I'll get some pics of the finished product and post them later...
