How about reflective white, Stands out in the daytime but would look stunning at night when the other cars headlights catch it.
Hmmmmm. Sounds interesting, do you have a sample for me to seeeee []
Our pudsey bears on our car was done in yellow and red reflective, the white is pretty much the same, looks like police cars etc, are you at the meet on friday? if so i'll try and get a sample. [Y]
