Welcome to the FFO!
Not sure which trim you seek.
Unless I am wrong, to me it looks like the seam sealer in the joint is coming up. A body shop should be able to make that repair.
I think that would 100% work but it is in black and not silver .. I would have to replace the other just so it would match I think .. I wonder how hard it would be to paint match the car for just a piece of trim. prob cost more than it's worthOK got it thank the picture makes a world of difference
