I always love it when someone makes a product that performs as advertised. One of those products is the Doctor ColorChip Automotive Paint Repair Kit.  Often imitated, the original is still the best. Follow the directions and work only on a small area at a time and it works wonders.  Dab on some paint, smooth it before it dries, use the blender as directed, and then buff to polish.  No more touch-up paint lumps and near color-matches — perfect blend to your factory paint code.  We used it before on our 2004 MINI.  The photos below show it on our 2004 Jetta.
