Large sharp stones and a shovel full of large gravel is useful. Strap the tank to a cement mixer and run it for an hour. Reposition the tank and repeat. I've never tried any slosh sealant.
Have also welded plenty of tanks, MIG and oxy-acetylene. Fill the tank nine tenths full of water and weld at the top.
