I helped a friend cannibalize a Toyota mini van a while back and realized there was a LOT of sound deadener mat in the roof of one of those suckers. Ready to be scrapped and recycled.
Alas no foil covering one side though.
As to no logo showing? Good Luck with that...
Isn't that what graffiti painters are for?
I think even tinfoil has a logo on it now.
Must drive tin foil hat makers crazy....
