While I was doing other stuff, I've pretty much completely removed my interior paneling. The insulation looks pretty scant and pretty old and I was thinking it'd be pretty easy to replace. Anyone know of any good automotive insulation?
It'll be good for temperature and sound!

duplicolor rubberized undercoating with sound deadener, can be found at wal-mart or Benny's. I use that and 3-part expanding foam for my trunk sound deadening, but it can work elsewhere too (in fact, my whole car will be covered with the **** in like 2 weeks).
