I have some small paint chips on the bumper of my 2010 Audi A4, and I was thinking about having a mobile bumper guy spray it over with factory paint. I was then told that the Audi paints change color over time, and so Audi repair shops will account for this when "blending" the spray over color. If the color is not blended to match aging, it sticks out like a sore thumb.
Of course, this means that instead of paying a bumper guy $300 to fix it, I have to pay the body shop around $750 to do it. Is this true, and what can be done about it?
