james get the peel and stick version of dynamat or edead whichever you decide to go w/. the spray is just not worth the effort. it is very messy and has a tendency to drip down and around where ever you spray it. so basically it covers other parts from where you spray, sections that didn't need to be covered in my case. i would not recommend the spray unless there is absolutey no way to stop the rattling in a very weird sopt on the vehicle.
Lol 2 layers of fatmat on my lid and still rattles like a b.tch, think i need to hit up the part where my amp is mounted upside down between my 6x9s and more of the hollow space inside my trunk lid....still got like 30 ft^2 of fatmat just need to stop being lazy and put it on...
zac i bought a bulk pack of dynamat off ebay for about 120 shipped and it includes 9 sheets of dynamat that is more than enought to do a whole trunk and would make a signifcant difference and improvement in the rattling and spl of your subs.
well i was gonna put mats over the concrete... i just had a random thought that came outa nowhere... i just figure it would be good to weigh my trunk down as much as possible then lay out a couple of layers of mats
