Chrome is insanely Hard to brush, its like brushing a bg, its all pure reflections bending in the shape of the object, you could use parts from the bg and just c/p ontop of your bumper and then Bend it in the correct Way, no colours or such Will be nescensairy since the chrome is as i Said before, only reflections
