To the o p, I understand your sentiment of wanting to preserve a trophy bike, I have a 3rensho that one of these years I'm going to strip and repaint in the original colors, but then it is going to become a wall hanger, as others here have recommended. Put the bike In Your Den or man cave and look at it every day. As long as the bikes indoors, it will last forever. Dust It Off once a year and it will be good as new.
