heh im in the middle of luner and rancid i live in a place called bourton on the water lol, about 30 mins from stratford, and 30 mins from malvern lol,
u can get ali and lead flashing tape, which is pretty identicle to brown bread, tar with a metal layer on it, ive done my boot in this stuff, did the floor and rear arches in it, and did the boot lid with a layer of flashing tape, and then filled it with expanding foam, its like a solid mass now, and the only thing that rattles is the rear wiper which im gonna take off soon ne way, only other prob is if the volume is up to high, the rear glass on the boot lid flexs like a b**ch lol
