Radiator Problem -- Can it be patched???

[eric at xmission.com]

Today I flushed the cooling system on my wife's Cabriolet. After refilling the
coolant, I discovered that the radiator has a crack where the upper radiator
hose attaches. I've done some research and it seems a new radiator will cost
around $320. I've also read that people have had pretty good success fixing
similar problems using something called JB Weld.

Does anyone have any experience with JB Weld? Is it worth trying to patch it
or should I just buy the new radiator?

I'm assuming that if I'm going to pull the radiator and replace it, I should
also go ahead and the the TB at the same time.
