Flyboy Dave, have you ever polished aluminum? When you rub on aluminum it produces black residue, and lots of it. Give it a try, you'll be amazed. You can start with the pipe on your .61RF
Yes, ChuckN....I am aware that polishing aluminum will produce black, but contrare....
a loose, or rubbing pipe won't produce all that black goo....flight after flight. It simply
isn't possible....think about it.
Dave.
