Cracked Catalytic Converter shield.
Has anyone found a replacement heat shield? This the the right side. Or has anyone come up with a repair?

 

The only thing I can think of would be something like this:


You could re-cover the whole heatshield with this stuff for longevity, though you only have about 5 minutes before it starts to cure.

NB, I haven't tried this myself, though I would if I needed to.
