We had some body work done on our 2003 Accord, and they did a poor job
of matching the colors between the hood and fenders. When I pointed
it out to the estimator, he said they must have used (too much or too
little) of the metallic particles. Causes the paint to reflect light
differently, and gives the effect of two, different colors. He had a
term for it. Duffing or something strange like that. Anyone know
what it was?
