Changed my mind about using JB Weld on a radiator crack
I was dead set on replacing my whole radiator after a 6 inch crack showed up in my old Civic. Then I watched a video where a guy pressure tested a JB Weld repair on a similar crack and it held at 15 psi for over an hour. Has anyone here actually gotten one of those patch jobs to last more than a few months?

My buddy's truck had a hairline crack in the radiator for like two years after we slapped JB Weld on it. We roughed up the area good with sandpaper first, cleaned it with brake cleaner, and let it cure for a full 24 hours before adding any coolant. It started leaking again after a really cold winter though, so I wouldn't trust it for a daily driver long term. Did you clean the crack out with something like acetone before applying the epoxy?
