Cleaning carbon fiber bicycle frame.
The wd 40 will leave a slick film that makes it easier to wipe off dust etc.
It will nicely touch up clear coats over natural carbon frames.

Unless its mud mucky water etc just drops off and when you get home a quick hose down with water is usually enough to clean it.
Touching up carbon chips can be as simple as dabbing on some clear nail polish.
Yet as with any bike it s never a good idea to aim the water directly at bearings headsets cranks etc because that can wash the grease out.
