I've had recent excellent (though not guaranteed) results with Wurth cooling system sealer - a cheap first try. Best one I ever did was about a 1/4" inch hole in a Healey 100 corroded waterpump in the middle of Mexico for a Frenchman. Water was pouring out faster than he could pour it in. Five minutes before the start, I said "No guarantees, try this." and gave him a bottle of Radweld. Next day he said "C'est magnifique" or similar. Good job he didn't beat us. Happy days.
