my rear bumper was scratched and repainted, and now it doesn't shine like the rest of the car does, very dull color. when i bought the car i also bought the clear coat protection, but the bodyshop said they put in clear coat as well and it's the best they can do AND they can't tell any differences.
i don't think i'll waste anymore time with the bodyshop cuz it clearly shows they are not gonna help. i brought it to the detailing shop that the dealer uses as their detailing shop, they told me to bring the car in tomorrow and they'll see if they can make it shine like the rest of the car does, but they also said "it might not work cuz the paint might be too thin."
now i'm all clueless and worried that this huge difference is always gonna be there, does anybody have any suggestions on what i should do?

car is an 02 coupe, satin silver metallic
