Steering Wheel Repair

[Henry/Kokomo]

I'm working on rebuilding steering components for my '30 AV8 Roadster. I have a 1930-something Ford wheel in pretty good shape with the exception of two cracks in the rim where the original material has apparently shrunk and pulled apart. Question: Is there any advantage to buying one of the commercial "steering wheel restoration" kits versus filling the cracks with JB Weld or an equivalent product?

Thanks in advance for all input and advice
