I had cracks in the fenders of my Willys Jeep that seemed to be caused by vibration and hitting the occasional tree. I fixed them by drilling a hole at the top of the crack (to relieve stress and stop it's spread) and then brazed the crack shut. That was before I had a mig welder but it held up fine. Now that I have the welding outfit I would probably weld the crack shut and grind it level.

The fenders are hung in such a way that they get exposed to quite a bit of stress and eventually they fatigue and crack. An extra brace rod or two may help a lot.
