hey this thread has been sleeping for a bit just figured I would chime in. The brillian silver is one of the most difficult colors to blend. It was explained to me from the body shop I took my car to when I had the hood repainted from a accident that the nissan silver has 3 types of crushed pearl in it. When the cars come off the factory line they are painted in batches. Now if you take a bumper from one batch and mix it with a car from another batch then it will stand out like a sore thumb. I have pictures of my Z from the dealership where they are showing the passenger side of the car with the sun hitting the back end. The gas cap, bumper and side of the car are 3 different colors because of how the sun is reflecting the silver. OP you posted a picture of your car with it in your garage. The bumper is getting sunlight but the side of your car isn't because obiviously it is indoors. The silver that we (and other Z owners as well) have purchased, possibly with other colors as well, are very translucent paints. Plastic does reflect paint differently than metal and it does cure differently than metal also. Did carfax turn up anything?

Nope no accidents or anything on the carfax, only one previous owner and car looks to have been babied. I honestly learned to just accept and live with it, sometimes the paint on the bumper almost matches perfectly, it all depends on how the sunlight reflects off it.

Thats exactly what im sayin. Its funny how in some spots it looks spot on and when it doesnt have the same light its a different shade. Love my car reguardless. Its like a 2nd wife with tan lines lol.
