What's the solution to the sunroof rattling?

I've had some 405's through the years and all do rattle from the sunroof.

My quickfix always was to tilt the sunroof open and the rattling goes away, but maybe someone here have found a more permanent and proper solution to the most annoying problem with these cars??

I have exactly the same problem, help is really appreciated

I have that sound too, I think it might be the wind spoiler.

Indeed it was the source of the noises. Although I temporarily fixed it is there a proper way? I don't want to think that all 405's with sunroof make that noise.
