Best way to stop trunk rattling?

I have a 03 Altima 3.5 SE and the license plate area (not so much the plate) rattles a lot and I was wondering what is the best way 2 go. I heard Dynamat but that stuff is so expensive. And If I do buy it where is the best place to apply for maximum quality sound or hopefully no sound.

Take the trunk lid off and your rattles will go away. Seriously, dynamat won't get rid of rattles if you don't know where they are, so don't just go blanket your car in dynamat and assume the rattles will be gone. You need to hunt them down individually and come up with a way to eliminate them. I have used rubberized undercoating and felt glued to panels that rattle. Trunks also have an adjustable latch that you can move down and that usually helps. Dynamat behind the plate plastic part the plate mounts to helps as well.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.
