Annoying rattle/vibration!!!

Mr&Mrs

I recently got around to having my Amuse wing put on and now when my sub is bumping just a tiny bit I get a vibration on the lower, top portion of the wing. I am an audio idiot and the best thing I could come up with to combat this is fill the wing with spray foam.

Will this fix the problem? How hard is it to fill a wing? Im screwed if I miss a spot. I also do not want to add 40 lbs of foam to the car! I already have added enough with all my carbon fiber and wheels. Plus that stuff makes a huge mess of anything it touches.

Thanks!
