When I was looking for a door Dronsfields had plenty of silver boot lids. Howard is correct you will still need to paint it as it will look odd. Try to get a silver one it will reduce prep time but it will need to be blended into rear wings. When I had my boot lid painted it was £90
so it will probably be cheaper to just get mine filled and sprayed by the looks of it, as it is only a penny sized dent and key scratches, thanks for the info
