It is well worth removing the wheels and applying primer and then a finishing coat to the brake calipers when your XF is new as the factory finish does not last too long and the calipers look scruffy very soon.I did this on my last Jag and after 3 years and 72,000 miles they cleaned up as good as new by applying a non acid wheel cleaner and hosing off.The choice of a final colour is personal but I found that silver was very durable on my last car or use as near as you can to the body colour of your car,so I have done mine in Azure with a spray can of paint mixed by Halfords and I am told they look great when the car is moving.
