Can you use JB Weld on a cut sway bar or metal car part?
Accidentally cutting into a suspension component like a sway bar or rear stabilizer link leaves people wondering if using steel-reinforced epoxy like JB Weld can safely fill the gap and hold. Relying on makeshift fixes when the right tools or replacements aren't immediately available creates uncertainty about whether the part will hold under stress or weaken the vehicle.
