i dipped all my tool handles in neon pink Plastidip, or whatever that stuff is called, for the same reason. i also put duct tape on electronics and cover it in graffiti. don't worry about cosmetic dings; it's a good thing in this case.

as for the camo subject, i find that jeans and a t-shirt is pretty universal. i always wear my drabbiest clothing during the X-Mas season; i find the beggars tend to leave me alone when i'm wearing my old A2 and a wool watchcap.
