There is a kind of foam padding found in the trunk of my 2nd gen. It's glued (practically welded) to the floor below the carpet and carpet-pad in only a few locations (the spare tire well, below the jack arm, and just behind the rear bench seat). I'm trying to remove it because I'm going to re-surface my trunk with a rubberized undercoating. Has anyone figured out a way to remove this stuff in a hurry?
