Hello everyone,

My friend's Mercedes GLC has some issues about the matte chrome door trim. Its looked like tree sap or something on the surface , but actually it's already ate below the surface (look at pics)
My question is: is there anyway to fix it!
Further question (optional) How do they make the matte look chrome like this one? Is there a clearcoat or something to make it look matte, because I can clearly see the shiny chrome below the matte coating.
Thank you

What have you tried on it so far?

I've found that a lot of the decorative trim pieces on newer vehicles are actually clear coated like the paint. It may just need to be compounded and polished out. Obligatory "Always use the least aggressive method to get the job done" first, comment. I just finished cleaning up some etched water spots on my wife's A/B/C pillars and they turned out like new.

I don't know what I'm talking about, but that actually looks like it might be anodized aluminum. If the anodize has been compromised there isn't going to be any way to fix that, short of replacing them, wrapping them with vinyl, painting, or plating.
 
In the pictures that I posted, the chrome trim at the bottom and top also had the same water etching. It also cleaned up spotless after buffing. I'd find an inconspicuous trim piece and give it a shot to make sure what the material/finish is.

This is a good point. Obviously, it's impossible to tell without seeing it in person, but to me these pieces look to be coated and that this is water/road grime etched into the finish.

That looks like a plastic film over it. Think I have seen it before. The film starts to peel compromising the piece.
 
Try a light polish and be careful not to lean into it too hard. If and once corrected, I would recommending getting a PPF installer to wrap that trim up. I even tell people to get their B Pillars wrapped as they scratch easily and can only be polished out so many times effectively.

Is that an F-150? If so did you put a coating on them to protect them?
 
Subscribed, interesting topic, curious to see what fixes it
