So I am doing some repairs to the rear tow points on my 81 Hatch, and I'm getting tired of babysitting the glue that seals the rear body panel to the floor.Every time I try to cut/weld something under there the glue catches on fire and burns up some of the wiring.So what is the best way to remove the glue so it stops catching on fire so I can focus on the task at hand without worrying about if the car is gonna go up in flames or not.

 

I tried scraping it out but I didn't have much success.I dunno wire wheel?

googone and a thick scrubbing pad usually works for me

dry ice?
