DIY Sound Deadening Trunk Lid

(1/1)

silver78:
My trunk lid sounds like a Pepsi can when you tap on it and the skin vibrates against the support structure underneath.  I decided to try this trick which is not OEM but it worked and made me happy.
 First I modified and lengthened the spray tube with a piece of thick wire so I could reach further into the supports and the foam isn't visible through the holes unless you really look in there.

I also applied some Killmat to the inside of the rear quarter panels, trunk floor and the back seat divider.  Sounds like a nice thud now instead of that tin hollow sound.  The trunk lid still pops up when I unlock it.
