On a dark colored car it would be cool, but I'm not sure on white ones. Can't see it before me how it would look... Btw would paint stick to the mud flap in the long run? You might be better off, just letting it be black. :monster:
If you can, try to modify a pic of your car ie photoshop, just to see how it would look
You do know that Infiniti did sell factory colored mud flaps for the 96 P10's right? You can buy the white ones to match from the factory and then you don't have to worry about the paint coming off that flexible rubber!
