You can also add material to the inside of the plastic trunk panels themselves. But you need to use contact cement to get good adhesion.

Thanks for your feedback guys.

I'll be ordering another Superlite Bulk Pack (12 sheets) to put a second layer on the trunk, do both skins on each door and the kick panels.

Fingers crossed it all goes well! :)

Too bad you couldn't have given us a chance.

or try second skin.....

Here is Australia, Dynamat is the easiest and most readily available product, hence I've always stuck with them. Besides, I've already got the first layer of Superlite down so I'm keen to test what another identical layer does.

All else fails I'll try one of the suggested alternatives! :)
