Hi guys, I'm a ASE certified Automotive Refinishing Tech with over 20 yrs in the field and I've been working as a Technical Sales Rep for a mayor Automotive paint company for the past 12 yrs (company will be unnamed) When a body shop or a dealership has a paint related problem they call someone like me.
After looking at these revealing pictures, I can tell you that this has nothing to do with anything rubbing together and has everything to do with lack of adhesion. This can be caused by improper cleaning or lack of the plastic adhesion promoter that’s needed for paint to stick to a plastic part. What scares me is that this doesn't look to be an isolated case. These kinds of things happen in batches, and will continue to happen until someone catches it and changes the procedure on the manufacturing level.
Lets hope that the rest of the bumper is ok, because in my experience a quick fix at the dealer will only fix the obvious problem but if the rest of the bumper has the same adhesion problem it will show somewhere else and eventually the bumper will have to be removed and striped to the raw plastic. Then the bumper will have to be cleaned, prepped and sprayed with a proper adhesion promoter before it can be refinished. A LOT OF WORK! Several days worth.
Well these are my two cents.
