The track which my screen door slides on has weep holes. One of them finally gave way, leaving a gap ( see photos). I cannot find this track style anywhere that I, as a general consumer, have looked. How can I get this fixed or fix it myself? I prefer to not have to replace the entire assembly if I can help it.
Is there, perhaps, a filler of some sort?

Repaired
Based on the selected answer, here is the repair using multiple tiny clippings of aluminum from a can of dog food and judicious application of JB Weld. The hold is extremely strong when pushed and the roll-over is fine. There is no longer a weep hole here. While I did coat the piece that lays flat on the surface, the epoxy either came off or receded; I plan to apply more epoxy to complete the seal. Excess JB Weld has flaked off the track.
Update June, 2015: still holding strong a year and a half after the additional sealing. I just moved, so this is the final update.
