    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

          Eastwood has a few paint products but then again so does Auto Zone. Ive wire wheeled hundreds of bodies and used the Dremel in all the small areas but they eventually dull again.

            VM carb bodies are zinc. BS CV carb bodies are aluminum. Both use aluminum float bowls and tops.

            The only way I've found to make them shinny is to glass bead blast. It's gotta be fresh bead, not crushed glass.

              So what alloy is it?
              Does it contain lead or some other substance?

              How reactive is pure zinc? Not sure what this guy is polishing but it buffs up mirrorish

                  I dont know what alloy it is but its not pure zinc.
                  Yes carbs can be buffed up and polished with aluminium polish or various other metal polishes that are available but its a tricky job on a carb.
                  A dremel with stainless steel wire brushes will shine them up but not the same as a polished finish.
                  I think what Chuck was aiming for was a dip of some sort that will not only clean the carbs but leave them looking pretty shiney as well, with no elbow grease involved.
                  I have tried almost everything available on the market and there is nothing i have found that achieves this.
                  However i have developed a product that will clean them to a clinical standard, and leave them a nice satin finish, which i use on all the carbs i refurbish.

                    They clean up nice using a vibratory deburring machine.

                          Chuck, Google 'zamac' or 'mazac'. Different terms either side of the Atlantic, which relate to the same alloy. Zinc, aluminium, manganese and copper.
