Yeah, it will, but you won't get the results you're expecting from it. All it does is address one issue to the problem. It simply adds mass to the body panels, but doesn't fill the spaces between them. That's where most of your vibrations come from.
If/when you get your car back on Monday, if you notice any vibrations or anything else, let us know and I'd be more than happy to help you get what you need to fill your doors with foam. It's well worth the time and only costs about $30. It also helps your front door speakers in that it forces sound to come out of the front of the speaker as opposed to escaping to the side or simply vibrating.
