Subject: [CR]Restoring old parts

I often restore aluminum parts by first removing tha anodizing (CR archives), then buffing out the dings and scratches. I have found the fastest way on aluminum is to use a buffing wheel with stainless steel compound. Yes, there is the sling it ding it factor too if you aren't careful. It looks great to me, a high polish like steel on aluminum, but of course oxidizing occurs without the coating and the aluminum gets cloudy soon. Still, if you polish it up every once in a while with some type of product, it looks good. If the parts are steel, there is nothing like a good buff job to make you say, "Ahhhh".
