I have a new OEM Mercedes bumper and after only two weeks I already have at least six white paint chips in it! I have never followed a gravel truck nor driven down a dirt or gravely road, so no excessive exposure to flying rocks or debris.

I'm assuming the paint shop just did a crappy job of painting, since it comes from MB primered. I want to be somewhat informed when I go back to the shop to complain, so for you paint experts what do you think they did wrong???

It could be the fact that paint from body shops take a month to cure, meaning the paint on your bumper is still really soft.

I wish that were the case... but it was painted over three weeks before I picked the car up, so it had almost cured a month.

I also had the same issue. took it to a body shop after someone backed into my front bumper while driving and paint chips showed and even the paint on the hood on one spot has started to fade vs i took my car 6 months ago to another body shop for other work and no problems what so ever

Is it just bad prep? Not sanding the primer enough?

GT-ER

Paint is too thin and not enough adhesion promotion.

irondad

Adhesion promotion? Does that mean it wasn't sanded enough?

And possibly not enough Flex blended into the paint.

GT-ER

No, although that may also be a problem but it's difficult to know. Adhesive Promoter is a chemical spray that promotes the adhesion of new paint to old paint or plastic.
