Fat Matt rattle trap is what I use for my vehicles. You can buy it on eBay it's thicker and tackier than dynomat making it a better product for less money. In my truck I did inside the dashboard under the rubber floor mat inside the doors behind the seat and under the seat. My truck has zero rattles. The stuff really helps a lot and inside my doors I did multiple layers to really deaden them.
