Covered the inside of the bootlid with Flashband yesterday! Very, very good stuff. I used Evostick Flashband (from Woodies) and it's brilliant. It's got a metallic cover on the non-adeshive side and is really pliable and very sticky. When I close the boot now it has a really nice heavy sound (akin to a VW or BMW) - sounds much more expensive and less tinny.
Gonna do the boot floor and walls today and the 2 front doors and (hopefully) under the backseasts next weeknd.
Can't wait - reckon the car will sound totally different to drive (more solid).
Best 13 euor I've ever spent on a car.......
