KY Jon,
I think you understand my question best. The rust must be stopped and removed. That is the way to preserve the gun for the future.
French Gray??? an alternative that preservse the metal and protects it. ON a gun that does not have historical or high collector value, it is one of the alternatives I have done before.

PS I can afford to do whatever is reasonable, it is not a question of money as much as how will it come out with all of the pits and can they (or should they) be fixed
