I have been the most vocal about it and have caught a lot of flack for it from many of the FI guys. Oh well... just trying to help the community.
Anyways, Modshack, that's what I did... a coating of damplifier topped with Luxury Liner Pro in the hatch. It made a small difference but I'd need to do the entire car to be most effective. I did get rid of some hatch rattles, though, so that was nice.
