First of all hello everyone, I'm a new Grand Prix owner and love these forums and all the useful information!

So i had my car about 5 minutes after driving off the dealership and I got rear ended! My car is a silver GT sedan. When the body shop replaced the rear bumper at first they painted it all silver, I pointed out the inset part between the exhaust tips is supposed to be a darker gray color. So they took it back in and fixed it. Now my question is this, is that gray section supposed to be high gloss like the rest of the bumper or more of a semi gloss matte finish?

Any help with this would be greatly appreciated!

Thanks, Mike
