Hey guys, I recently got an m sport bumper for my car from a trusted vendor. I had a Bmw body shop do the work and was set to pick the car up today.
Got a call from them and apparently the paint was peeling after they tried detailing it. I haven't had a chance to go and check the car and see what exactly is wrong. From my basic understanding of painting, I'm assuming that they didn't prep the surface enough? What else could they have done wrong for the paint to peel like that? The bumper didn't come primed and they never mentioned using a primer either. My previous experience with an eBay bumper was similar but the shop I had do it specifically told me that they had to spend extra time prepping the bumper for the paint to stick. If someone with more experience can let me know what they think could be the problem, I would appreciate it. Last edited by BimmerF32_430i; 12-18-2017 at 04:07 PM.. |

You should not even wax a freshly painted body part for at least 2 months, let alone paint correct it.
How long did you wait from the part being painted until it was detailed? |

I haven't even gotten the car back yet, but they finished painting 3 days ago. I think when they meant detail they meant just washing and cleaning the car.

Shops paint plastic all the time (ie bumper)should be a no brainer to get a decent finish.

which is why I am so confused as to why this BMW certified collision center cant get this right. am i right in assuming that even if the bumper comes in a non-primed and non-OEM quality, that this shop should easily be able to prep and get the paint to stick?? it seems like a shop that works on thousands of cars should be able to do this..

While I agree they shouldnt have a problem if they're experienced, just curious what brand bumper did you get?

With those prices they're obviously Asian imports, which are usually OK, but not always. I assume that the factory bumpers are made to accept paint without special adhesion promoters, but aftermarkets might not.

Its most likely the primer that came (or was applied) on the bumper.
I've gone through two Selma (GoodGo) bumpers which are known to be one of the better aftermarket bumpers and the second one had a similar problem. My shop painted it and the paint literally started peeling. You knew it was the primer because the primer was grey and when the paint was peeling it uncovered black which was the bumper colour beneath the primer. They had to strip the entire thing and reprime + paint. Never had the problem again.
