“I was on an extended 4 wheel drive trip with my car club in the Great Victoria Desert (which is actually in Western Australia). This is an extremely remote area.
I accidentally tore the tailpipe out of my rear muffler on a rocky creek bed. We used a corn tin, a few screws and "Knead It" to make a very successful repair. This lasted 500km and more of off road travel plus 1000km on road back to Perth. The repair was still holding when I got the muffler replaced!”
