Faded switches

[Zolpidem]

Ciao folks, do you have any hints regarding repainting the symbols on faded and used switches? As you can see from my pictures, the heating controls have lost the blue and red paint making difficult to recognize them and I don’t like the way the power windows switch look like. Do you know any methods to repaint them in an easy and efficient way?
Grazie

Paint them with a very fine brush and quickly wipe off the excess...?? That's what I would try.
