No, it's just that when I saw the demo at a show I thought I couldn't live 
without that patching capability, but once I got the rods (four or five 
years ago at this point) I have never found a use for them.  They're bundled 
with the Eutectic rod for welding cast iron, a bunch of brass brazing rod, 
and several other filler rods in a vertical storage can I made out of 
several empty propane bottles years ago.  One of these days, I'll find a use 
for it.  For now, it has a good home.
