A number of features first seen on 100EX, the experimental convertible shown by Rolls-Royce in 2004, have been engineered into the new Phantom Drophead Coupé. Two of the most visually striking of these are the brushed steel bonnet and A-pillar and the teak decking for the rear hood cover. The brushed steel is machine finished to give a uniform grain before undergoing extensive hand polishing to achieve a perfect sheen. At the rear, the teak decking is treated with a carefully blended mix of oils to preserve a natural finish and a long lasting lustre that is as beautiful as it is hardy.
