I didn't try as it wasn't my can. However, my Gemtech Trinity had the same problem and I think I did try chemically soaking it with I think Ed's red a long time ago and it didn't work and had to have it jailbroken also.
Another point is that if there is a baffle strike, I can make a new baffle as an FFL / SOT or take it another SOT to fix it. You need to find a wizard like Ecco to fix welded cans if the manufacturer goes out of business which I never thought all the main people at Gemtech would end up selling to SW and it not like it used to be.
