He said he would address it with corporate but possibly its due to paint on metal (body) adheres differently to plastic (bumper). anyways he said he would do it as a one time courtesy and had it repainted.
its definitely better than having a yellowish bumper, it hasnt discolored since so i think its really a manufacturing paint issue or paint process issue.
I worked in autobody back in the 90's. pearl white is a very tough color to match and if the. bumper was painted seperate from the car, it wont really *match* 100%. Remember the Cadillac Allante?It had a gorgeous white pearl paint available. There was also a set of ppg videos and books about matching Cadillac Allante pearl white. Its not that the plastics and the adherence cause the difference, its that the paint has to be sprayed and layered the same for a good match. Adhesion promoters are used on the plastic parts, but the color difference is likely from thin, poorly matched factory paint. just my 2¢.
