Recently rear-ended in 2008 Highlander Sport. The back door (metal) and bumper (plastic) were replaced and painted. The new paint on the metal door is a much yellower shade of white, and the paint on the plastic bumper has a much more matte finish than the original body paint. Is this as good as it’s going to get, or is there a way to get a better color match? (No blending was done onto any original paint; the part seams separate the painted areas.)
While a pearlized finish is harder to match than some other paints, the fact remains that great strides have been made in color matching over the past decade or so. If your body shop was not able to match it properly, then they are not exactly state-of-the-art.
I would suggest that you contact your insurance company regarding having the paint re-done so that it matches, as your nearly-new vehicle now has decreased resale value as a result of the obvious accident that it experienced. A good body shop will do repairs that cannot be detected when viewing the body and the paint.
