I believe the Paint 'ruling' was loose, and it was agreed that a more blanket ruling was needed to protect the venues. The old ruling was that the paint would have to be tested for staining before it was used. This was not taken seriously, and the infrastructure was perhaps not ready to control or police it, which unfortunately became necessary. Hence the change of ruling.
You are right though, I am not particularly well informed about the Miami Paint 'Fiasco'. Don't see what it has to do with politics unless I am missing something. basically no-one was prepared for what it would take to acurately test the paint and make a clear ruling without holding up the event while someone nipped down the laundry-mat and washed the gear to test it out.
My knowledge of paint is sketchy at best and probably 5 years out of date, but the Titanium Dioxide info I posted is accurate to the best of my knowledge. I believe Benzine was also used to make the paint less 'wipable' by one manufacturer too. As Benzine is a known carconogenic this was eventually stopped. The paint is what is left when we have all gone home. It is going to be an issue that gets more and more important at future events. I suppose this new ruling is intended to negate future 'fiasco's',
and no, you didn't sound gay, not much anyway...
