If I can pick up a minty'ish' OG finish then I'll leave it so. If I can't, then I'll look at pics of bikes of the guys who have...and I'll refinish my scores to a standard that I'm happy with, without worrying about what other people think is the correct thing to do. I wouldn't powder coat a lovely ball-burnished PK, or a nice chrome TA but I would rechrome a rusty Pro Class or Supergoose.
