Castle® Quick Stop™ is specially formulated to repair leaks in the radiator, block, heater core and heads in cars and trucks. Quick Stop™ also provides good insurance against future cooling system leaks. The cellulose based, non-clogging formula should be added whenever the cooling system has been flushed. This will prevent leaking from the cleaning process.
