Check with an auto body paint supply shop. You can get touch up paint in spray cans. A lot of auto bodies and accessories are made from fiberglass. Krylon also makes a spray paint formulated for plastic. Sand the blank with 1500 wet/dry paper to give it some 'tooth' for the paint to stick. Use several light coats instead of one heavy coat.
Note: don't paint the male part of the ferrule. The paint thickness will change the fit and might cause sticking.
Thanks kengore, that's a good idea. I hadn't thought of touch up paint. I suppose a topcoat of a good hard car wax is called for too. Certainly couldn't hurt.
