How for over spec would the capacitor have to be for you to conclude it is not salvageable? Or would it be prudent to try to re-form it and then re-check ESR? If at that point ESR is still high, perhaps then you would discard the capacitor as dried out?
This thread reminds me I have a container full of ELNA Cerafine capacitors, 350V and higher rated, that are probably close to 20 years old and have never been used. I periodically think I should toss them, but I cannot bear to do it. I bought them from M Percy when he was selling out his stock.
