The C4 is very good - but for parts which are removable, like the front grilles, painting is the way to go. The C4 lasts a good while, but its not permanent (maybe a case for doing them under the trade description act!) and its prohibitively expensive.
Can of Halfords Satin Black is perfect - and 500ML is 9.99 or so.
