Got about 2hr 15min on the 60 this weekend. I got all the sound deadening out. Wasn't too bad using the air chisel on the floors and firewall... just don't stay in one spot too long

. I had to use a torch and scrape the stuff from the insides of rear quarter panels, that was fun!
Sound Deadening Removed:
Rust on driver side floor under sound deadening:
Oops...

don't stay in one spot too long!
