I was told my coin finish K20 should be treated as a bare steel gun. Keep coat of oil, vasoline or grease on gun and remove any discoloration with steel wool. Polishes mentioned will overshine. Coin is especially bad for those whose perspiration is especially salty, acidic and "corrosive". Dealer did not even want to sell me gun if I was naturally hard on bluing.


A Springer Spaniel, a 6# double and a fair day to hunt.
