Been working on the trim pieces while the car is at the paint shop. Some of the threads I checked previuosly suggested using a caustic cleaner like Easy-Off to remove the anodizng from the aluminum pieces for a better polish job. I tried using Mother's aluminum and mag polish with some plain steel wool. It's not a "show car shine" but it seemed to do a fair job without removing the anodizing.
You wont get good results unless you remove the anodize.Once its off,you can polish the stuff up to allmost a chrome like shine.Then you need to keep a wax on the parts to keep em looking good.3M perfect it II rubbing compound works wonders on the stuff once its ready to be polished.
