The headbadge from my 1980 (ish) Nishiki is in need of repair. The small yellow and blue section are fine, but the red sections (not sure if it's paint, or some kind of plastic) are missing.

Any sugguestions?

I tried painting it with a small brush, as well as masking & spray painting....but don't like the messy looking results.

And yes...I did look on eBay, but the only one I've seen their lately was the wrong type and was in worse shape than mine.
