GM bulletin on Perceived Paint Mismatch on Door and Quarter Panel Paint Appearance
Service Information
Document ID: 2346049 #09-08-51-004: Information on Door and Quarter Panel Paint Appearance - (Sep 10, 2009) Subject: Information on Door and Quarter Panel Paint Appearance Models: 2010 Chevrolet Camaro On the 2010 Camaro, the shade of paint on the doors may appear to be different than the shade of paint on the quarter panels. This appearance varies in severity based on different viewing angles and light conditions. This perception is more apparent with certain colors. Use this bulletin to help the customer understand the design of their vehicle. Paint Process At the time of vehicle manufacture, the complete sheet metal body of the car is painted at the same time (the body, hood, decklid and doors). The panels (doors, hood and decklid) are attached to the vehicle and in the proper position when it goes through the plant paint process. All of the panels receive the undercoat layers and top coat finishes using the same material, application process and final bake process. This continuity of process ensures a uniform paint application to the entire vehicle. The result of this extensive process is a seamless paint match over the entire vehicle. The only major exterior panels that do not get painted during this process are the bumper fascias. The bumper fascias receive a flexible paint application using a unique process. All of the paint used in the paint process is matched to a paint color standard, ensuring that the colors are consistent from batch to batch. This color standard also ensures consistency from vehicle to vehicle. Vehicle Design On the Camaro, the door to quarter panel angle match is the design intent. The geometry of the quarter panel provides a sporty definition and highlights the depth of the design. It is intended to show the color variation created by angling the body panels a few degrees. Addressing Customer Concerns Use the following photographs and descriptions to demonstrate to the vehicle owner that what they are seeing on their vehicle is not a color mis-match, but a intended design feature. This first photograph shows a paint test panel finished in "Wildfire" metallic. The white arrow points to the paint "standard". This is the paint sample used to ensure color consistency. This photograph shows the same paint test panel with a slight crease in the center, creating an angle in the panel similar to the Camaro door to quarter panel relationship. The finish on the right side of the panel has "shifted", creating a different hue of the same color. Note the arrow shows the paint standard on the left side of the paint test panel in the same position as the first photograph. This final photograph shows the same paint test panel described in the second photograph. In this photograph, the arrow points to the same paint "standard" used in the first two photographs but it has been repositioned to the right side of the paint test panel. Note the paint "standard" has shifted along with the finish on the paint test panel. ** Official Bulletin Document attached ** |

Even though the paint is mixed exactly, painting plastic vs metal will make a difference hue color. My 08 Buick (white pearl color) has this problem. Very hard to match, if possible? From a excellant Paint/Body Shop that paints Lexus Cars too. They (Lexus) don't seem to have this problem but probably has the best paint job out there. My thoughts. Gene

The color match "problem" at the rear edge of the door to the 1/4 is caused by the metallics and pearls reflecting the light differently since the two panels are at slightly different angles. This is what we in the auto refinishing world call "flop". All the repainting in the world won't cure it, just change it slightly.
I am not sure how the plastic is refinished on the Camaro but most manufactures do it separately due to the high temps used in curing. Some have a better process than others. It can fluctuate from car to car. If you have a bad match at the front facia (bumper cover) to the fenders and hood the only way for a seamless match is to reshoot the cover and blend into the a- joining panels. Trust me it's what I do for a living. |

Hi! I have a summit white camaro 2ss rs with the halo's etc. My question is has anybody noticed on their cars the paint is not finished on the inside corners and underneath where the halo's hid lights are mounted? I am talking about the area up underneath in the corners where the lights are recessed where the lights are recessed and it's not even glossy, you can actually see the primer coat with a bit of white paint spray! Any notice this too and if so is it normal as you can see there is no paint there up close!

I heard some of those Found On Road Dead guys have similar issues under the hood. If they remove the hood liner on their little ponies, all they see is primer and some overspray. Looks like Detroit is getting cheap all around!!

My summit white camaro is two tone for sure. This is getting so annoying, that i'm taking it back to dealer and ask what they can do about it. I understand the problem matching plastic and metal parts but c'mon mine looks like crap IMO. Anyone with summit white with same problem?
