Should I place asphalt on top or under this or just use the heat film ???? Thanks guys for any replies....alan

Your choice to put it on top, but don't put it under the heat film. Because I had the factory die cut asphalt insulation I added it on top of the sound deadening material.

Thanks Andrew, I was thinking that was the best bet,I just needed a 2nd opinion,thank you very much.......WHAT A BEAUTIFUL CAR YOU HAVE,by the way if possible e-mail me some pics of that car,that is 1 sweet finish,I would like to add it to my collection on my computer,somebody had some labor involved to get that type of finish.......thanks again....alan

Thank you Alan. I sent a few photos by email.
