💡 How does an instant radiator leak sealer actually stop antifreeze drips without clogging small tubes?

This handy fluid flows straight through your cooling loop and sticks right to fresh rust holes. Tiny fibers jam into fractures while system pressure forces them tight. Here is why racers trust this method:
- Locks hairline breaks inside heater core channels fast
- Bonds directly to metal walls without blocking main flow
- Stays solid under extreme heat so patches never wash out
- Plays nice with plastic tanks and brass radiator caps ✝️
