POLL-Paint or undercoat?

I used Rust Bullet (similar to POR-15). This is a rust encapsulator/preventer, and I will paint over it in the trunk area and anywhere else that may peek through with the body color.

From my understanding, putting a giant layer of dynamat all over everything solves some problems and creates a few more. Since it is a substantial enough layer, it is possible for vibrations to transfer through it.

ALSO- a buddy of mine used tar sheet crap from home depot, and then some tar based stuff he bought from a parts store, both were cheaper than dynamat, but contain asphalt which never cures and on hot days the car smells like a freshly paved street! :wack: :oops:

I am going with the Quietride Solutions insulation/sound deadening package. These guys are Mopar savvy and have measured several of my families' cars for templates.

Excerpt: Coverage: How much is enough? Always the first good question. You do not need to cover the entire panel--edge to edge. Cutting the Dynamat material into one inch strips and spacing it out over a panel to achieve a 30 to 50 percent coverage will give you excellent sound deadening characteristics.

The Knuckle Test: Rap your knuckles on the panel before you install any Dynamat to learn what a bare panel sounds like. Then adhere a one inch strip of Dynamat in the center of the panel.

Rap it again to see out the sound has changed. Add another piece of material to the left and right of your center piece, splitting the difference between the edge of the panel and your center strip.

Rap the panel again to hear how the sound has changed. Repeat this process until you are satisfied with the “density” of the sound level.
