Trying some JB Weld on a cracked radiator before swapping it out completely. Will it work?

[@davidcoupalbergeron2]

It need to be clean before application . Clean like you would eat on it . And it need a cure time . Sorry buddy

Sand down the crack, use high temp and slap ducky tape over it to keep it from peeling up when it gets hot

​@@MichaelDishmonthere was a crack on my water radiator pipeline. What I did was remove the corrosion part, sand and clean it properly, put some copper tape over the cracked area and finally other stuff just like this jb weld for high heat application and it works great. The longest part were to wait for the water to dry from the leaking area (which can be expedite with proper draining and blowing air) and the curing time (which also can be expedite if heat applies on the area before applying jb weld).
