Can't resist...Campi wouldn't that be two or more Campy Parts??
As far as cleaning...a gentelman that does aircraft restoration did a test on simple green (lemon) vs easy off oven cleaner. Simple green was more corrosive (they use it to remove exhaust stains). For polishing, if you get any dark left in(polishing residue) use purple sparkle glass cleaner it's not a very good glass cleaner but a great aluminum cleaner and if it gets on plastic...no ammonium to screw up plastic. Then seal it with Glass wax. Never dull and some of the others can leave a shadow. There are so many ways to clean/polish but if someone with more money than they know what to do with shows me that on a totally polish aircraft..I'll roll with it.
Btw that's once you get past the anodizing. That's the PITA for me. That my 2cents worth.
