I've painted a Jim Howle nose before, but it had a matte finish. (non-shiny). Don't know about a proKnows? I used acrylic paint and a spray on sealer (clear coat) to make it shine.
Leon said that a red sharpie made the best touch ups,but an all out repaint? Don't know...
I would go with a good quality acrylic spray paint, but primer it first.

I have glittered one before. I covered it with nose glue and dipped it into loose ultra fine glitter. It stayed nice for a long time. When It needed it I just repeated the process.
I used nail polish one for a touch up, left it shinny.
Nail polish~! Its great idea!
