I have read, I believe in Classic Auto Restorer, that the best way to remove
the soundproofing material is to find a source and purchase dry ice, chip it
up and put a layer down on top of the tarry stuff. supposedly it causes it
to chip and flake right off the floor. no scraping, no fuss, no
muss....haven't had the opportunity to try myself, though.
