I'm not a big fan of add-on "snake-oil", but I must admit to one very
dramatic demonstration of radiator stop-leak's effectiveness: Many years
ago, probably '99 or so, Jim Bounds drove my GMC a mile or two to check it
before doing wheel alignment. When we returned to the shop, there was a
steady stream of water shooting out of the lower portion of the radiator
where some road debris had hit and punctured the core. He sent a runner to
the parts store for a can of Barr's StopLeak, which he poured into the
radiator. Within a few minutes the leak stopped. I never had any leakage
from that radiator again before replacing with an aluminum one 10+ years
later! Honest Injun!
