Just a guess on the anti-freeze. The corrosive effects it had on
the steel tuning pin caused accelerated rust. The net result was
(effectively) a larger sized tuning pin or a smaller hole,
depending on perspective. If one could inject iron filings into
the t/p hole, the net results would probably be similar.

someone who used a seemingly effective solution composed of antifreeze.
Anyone have any comments?
