I was thinking of buying an old K31 Swiss army rifle and was wondering how much it would cost to re-blue or Cerakote one? It would similar in size and shape to a 308 hunting rifle. I don't mind doing it myself but it looks like all the better cold blue products can't be shipped to Canada, so I am inclined to have it done professionally. As an alternative, I might be able to get a rifle in almost new condition for extra $$ which would obviously have benefits beyond the cosmetics. I am in Calgary. Feedback is appreciated.. thanks.
