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.

Anyone have any comments?
