Plastic parts slightly off in color...

John,

Can u be more specific as to where you notice differences?

For example... My new scud, the front bumper IMO is brighter or darker red than the front hood/fender of the car.

My car was a 1600 mile car when I bought it and is confirmed as having zero paint work or sprays... Yet in good artificial light, I can see an obvious difference... Why it is different, that I cannot explain and frankly, being as picky as I am, it makes me crazy!

Btw, mine is rosso corsa 322 also

 

Even with a 360 with the same color, its exactly the same thing. My 360 has had nothing painted on it since new.

 

Not a problem I've seen on either my Rosso Corsa 430 coupe or on my 16M with 3 layer. Paint is a perfect match across all panels. Both cars needed detailing to remove paint imperfections/sanding marks as per usual Ferrari finish but no colour problems - sorry.

 

90% of the Ferraris I see or deal with have a small difference in the bumpers and rockers. This is normal. Usually the ones that match the best are cars that have a complete repaint or special ordered colors, those cars are pulled off line and painted at a different facility, not at the factory.

 

Could also be that the paint on plastic and on the metal have a difference in shade,
Once the paint is adhered to the surface. the paint on the plastic might give a deeper
look than on the metal body.

 

Spot on. I have sold new cars for around ten years and although it's a very small difference there is always a slight difference between how plastic and metal show the paint.
I notice it more on silver and dark blues. We have had a few people complain that the new car must have had a respray over the years.

 

That's how you know it's factory original!

 

sometimes it has a lot to do with what sealer/primer is used before the paint is laid down. When i paint cars and or have to repaint a bumper to match. I find out what sealer color is on every panel before paint is applied to match oem body color. Red paint you want to use a red sealer to minimize shade and tone issues. If you use gray which a lot of people do, and your layers of paint are different you will get the effect you are talking about. Since it take more red to cover gray sealer than red sealer.

This also happens with metallic as well! if a bumper is not sprayed the same way the body is longitudinally sprayed the metallic will flop and cause a contrast. You can not blend with metallic well, and I advise against it! There is a lot of repair jobs where silver in certain light looks darker or cloudy cause it was sprayed on top of the clear to give a blend into an adjacent panel. Causing a prism effect. Which you are essentially spraying metallic over a gap between metallic paint. Which is why, real shops, only spray the whole side of the car, not just a fender into door. And! if you have a insurance claim cause of it, please, spend the extra to have the whole side, or car done depending on accident. Silvers yellow out so any new paint you apply will look a lot more crisp. Where as Reds tend to pink, or orange out depending.

Also, the plastics used may heat up differently than aluminum (this is theory) but it might heighten the aging process of which paint discolors at.

 

Audis are notorious for this. Look up for example a white A4 from a parking lot.
The bumper color is WAY off from the body color. More grey / not as bright white.
