The only chrome bits on the bike that aren't bad are the crank arms and chainring. The stem and handlebars were quite terrible, and after my adventure with the stuck stem bolt, they've been replaced anyway. I'm going to try the silver paint trick for these and a few other once-shiny bits like the frame clips for the cables.
I found this in William Love's How to Restore Your Collector Bicycle (which is now out of print, darn it). Love is talking about cadmium or nickel-plated bits like fender braces, kickstands, etc., but I'm going to try it with chromed pieces. I figure they can't look any worse than they do now.
Good old "chrome" silver (shinier) or aluminum (duller) spray paint works wonders to touchup these...plated parts, but not necessarily by spraying them. First, wash and thoroughly dry all of the parts.... Spray the paint liberally on a paper towel, and rub the paint on the affected part.... The deteriorated portions are a bit rough compared to the rest of the surface, and the paint sticks to these areas while blending with the original surface nicely (Love p.64).
We shall see. This is probably going to be this weekend's project. I'll let you know how it works.
