- I don't think so. It is economical for junkyards to salvage the platinum-based
- catalysts now, why not the gold-based ones when gold is going for about the
- same price? The only potential problem is perhaps separation problems
- in recovery since the 'raw material' is likely to be a mixture of gold- and
- platinum- (and anything else-) based converters.
-
- Perhaps there will be social problems, people stealing converters due to the
- gold that doesn't happen now, due to the 'charm' you mention, but that's
- about it.
