I have a JBG 4 core brass radiator that has developed a slow leak when running or sitting. This radiator is now 13 plus years old. Unfortunately the Bronco did sit for years during that time. Assuming this sped up the process of corrosion with the radiator(not changing out my fluids). Through out its life it has cooled and continues to cool the engine well(not great). With that being said what's the groups thoughts on Bar's radiator leak stop product? Knowing this isn't a long term fix vs throwing new parts at the Bronco.
