well, I usually don't go ahead and try something I'm not familiar with, but in this case I ordered one of those Frontier 45 pads. I must say I'm impressed. My son hadn't taken care of his M70: surface rust on barrel and floor plate. That pad did a really good job. If I were to show the gun now, I doubt anyone could see any signs of the surface rust: maybe if they turned the gun just right in the light, but even then, it is very, very limited. thanks for the suggestion.
