Well, it's not really noticeable when looking at it at any normal distance... And I rather have it fixed than "reverberating" every single day.
But I guess you can just trim away any visible part of the "glue" if that annoys you (or ask them to do it right - truth be told I just noticed it a couple of days later when looking closely to see what the fix was; after checking it had really fixed the noise issue.)
But I can bug them next time I have to take my car to service...
