Only ever noticed the plastic fading as opposed to the metal panels tbh
Must be to do with the primer either way

 

I would imagine its down to a difference in the paint system used on the body vs the plastic parts.

 

subcrontracted bumper suppliers providing finished products to spec, audis from the last 5 years or so have had terrible mismatched paint IMO

 

Would it not be down to the heat a metal body would reach as opposed to the plastic front bumper, making the body burn through the paint quicker?? Only a guess

I've seen that with Audi's around the place too, especially A6's which is quite shocking considering what they cost!

 

its impossible to match colours on bumpers and wing as its metal versus plastic. some coulours do match well though. as for paint fade. its the quality of paint and depth of primer and paint

 

Its to do wit the quality of the lacquer guys and also temperature metal roofs and bonnets gwt up to..
