Soda can muffler end-cap replacement

Most of the time we can't wait 5+ days for a new part to ship, so you've gotta do what you've gotta do.  Since the aluminum on the top of a soda can is considerably thicker, this could work.  JB Weld should work at least temporarily, but in my experience it takes even longer than said in the instructions to let the glue set so that it can withstand the heat.  Since there isn't a whole lot of pressure put on the JB Weld, it might definitely hold.

UPDATE: If you don't want to use JB Weld and you want something superior to the OEM end cap, check out my $3 end cap replacement!
