I have a black Magnum and a black Ram Quad - I just could not face another black car. The graphite made a great alternative.

Also, I would ditch the duster. I started using one and began noticing small scratches on the black cars. A litttle work and the scratches are gone. Now I never dust dry - always use a detailer spray and a high quality cotton terry towel and no more scratching. (micro fiber just ended up holding too much grit)
