I moved the post for you, you should get more replies here.
The best fix is always repairing or replacing the radiator. Having said that I prefer the ginger based stop leak products, many automakers use them on the assembly line. I would try one of those, and get a lower pressure radiator cap. You'll have to hunt around for one and perhaps cross reference it from another older vehicle. You'll need a good parts guy to help, or some creative Web searching.
The lower pressure cap will help by lowering the pressure in the cooling system. The downside is the boiling point of your coolant is lowered with less pressure. That may or may not be a problem. I have done it with beaters that had no overheating problems with success.
Bottom line the proper repair is always best. Good luck.
