Some folks have inquired as to what plastic polish I use. Currently, I have a bottle of Blue Magic, but I also like Meguiars. It is a liquid super-fine abrasive available from most autoparts stores. I use it as a final prep polish, than apply some carnuba over that (or Paragon). It seems to keep the oxidation at bay on my vulcanite stems. You can apply by hand to take out small marks, scratches, etc.
