Paint for painting dsi?

Electronics do not respond well to spray paint at all in fact spray paint can ruin ANY electronic device...Go and have it AirBrushed by a professional that is used to working with electronics However if you decide to alter it in this way you will decrease it's market value so it is not to be recomended the best thing you could do would be to go to your local game store (or walmart) and buy a DSi cover case for it(anyone behind the counter should know what you are talking about) ...Good Luck
