Has anyone repaired a cracked coolant reservoir?

I just replaced the coolant reservoir and since the engine was out I did not have to destroy the old one to get it out. Since I hate to throw away things I got to wondering if it would be possible to fix this.

Plastics are a mystery to me, is there a spray on coating that would seal the existing and future cracks (I have my doubts). Or is there a sealant that could be poured into the tank that would seal and strengthen the bottom? It would have to adhere to the tank and be flexible enough to not crack itself.
