dynamat is WAY too expensive. or u can try rammmat or the mcmaster stuff or the partsexpress stuff. from just doing my front doors. i bought the mcmaster sheets and stinger roadkill spray. the mcmaster is great for inside the door (flat surfaces) but was hard to do the interior of the door due to the non flatness. it didnt come out as great as i thought. weather is getting colder and i'm running out of time. i'm gonna pull the mcmaster stuff from the door panels (not the door skins) and use something that shrinks when heat is applied. i sprayed the stinger on the doorskin over the mcmaster. i didnt spray the door panel.
