Polishing is somewhat of a black art. Prying secrets out of journeymen can be an exercise in futility. We are not sworn to any secrecy, such as a magician, nonetheless, the best techniques for polishing are actually not readily available on the web. Oh yes, you can read or watch videos with guys using this polish and that wheel, and the results are always amazing. I have discovered something however. Not all aluminum is alike. The aluminum on a V8 valve cover is much softer and easier to polish than say, a GL1000 valve covers. And something from a 1970 Triumph is harder yet. So hard, it seems like you are simply buffing the tarnish rather than the aluminum.
Anyway, here is a secret I have not told you yet. I am frequently asked how to get the black polish residue off of the part easily. When I first started, I used mineral spirits or lighter fluid, followed by a hot water bath and mild dish soap. I still had to rub some of the polish off, and the mineral spirits would leave a rainbow if not completely removed. And acetone worked great, as long as you wore a gas mask and chemical gloves. Not long after I started I found the secret. And I am surprised none of my customers have "sniffed" it out.
So here it is. Peanut Butter. Not kidding. Yup, smear some creamy peanut butter on the black residue, wait a minute and then wipe it off with a clean towel. The towel quickly turns black. Wash the entire assembly with mild soapy hot water and rinse. Done.
And a warning for folks doing this at home: Do not attempt this if you are stoned and haven't eaten that day. A peanut butter timing belt cover ain't so good for your teeth. Just sayin'.
