1. Black (Satin? Gloss might mark too easily, although mine seem to be holding up okay. Don't think plasti-dip matt would look good)
2. Red (agree with others that the photoshop pic in your thread may not do the colour justice)
3. Silver (If it ain't broke....

)
How about getting them wrapped with 3M 1080? You could do it yourself, but for peace of mine get an authorised dealer to do it. Then if you don't like the colour you can have it done in another colour, or removed, and back to the OEM colour.
Good luck choosing...
