re: Removal of Tar Type Undercoating

["Giller,Bruce C." <bgiller@domain.elided>]

	The same applies to linoleum floor tiles: get them cold enough and they
shatter.  But since you don't want to turn off the heat in your house,
the way to do this is to apply dry ice (solid CO2) on the tiles to
'freeze' them, whack them with a hammer and use a scraper (I like to use
a wallpaper scraper - very stiff and about 2.5" wide).  

	You'll need to insulate the dry ice from your hands somehow (thick
gloves & tongs perhaps) but I'd think that it would work on your cars
undercoating as well.
