The best thing to do, is order a new radiator. You can go to radiator shop, get them to quote you a price on new radiator. That stop leak might seal a small leak from the inside. I dont like to use that stuff. If small leak in metal/brass radiator tank, The radiator shop might be able to soldier it for you, might last a little while?
