what do you guys use to take off a rounded/stripped plug? the 1/2 socket isn't big enough to fill the hole and it's rounding it up more. here's the list of what i have done, but that plug is still stuck (nftw). 1. i tried inserting metal sheets with the socket. 2. went to a muffler shop and have them weld a socket on the plug. 3. sprayed lots of wd40.
