Stops leaks as they occur. You may not need to change that radiator! Sealite seals a leak quickly and permanently without clogging the radiator or heater matrix as it only solidifies as a leak occurs and the treated water comes in contact with air and the hot radiator. A leak from a large hole needs to be slowed with steel wool, or steel wool and blue tack. It is good practice to flush and refill radiator before using any sealant. Two cans are recommended for large radiators.
