I used the copper penny technique and I removed the rust. However, once the rust is gone, you have bare metal underneath, so depending on how large an area we're talking about it may need to be refinished.
I've done this to my nickel plated model 57

Correct, new pennies are only copper plated over zinc. I have a bunch of 1960's pennies and I used one of those.Has to be a true copper penny .. Im thinking older than 1982??
I have used copper pennies several times in tbe past .. seems to work great
Yes...if we just point and grunt most people would understand.I think "surface rust" is a common enough term for all of is to understand and be familiar with. "Pedant" on the other hand is a word more people should familiarize themselves with.
"...surface rust" No such thing. The formula for rust is: FeO (OH). The formula for Iron is: Fe2 (subscript 2). When Oxygen and Hydrogen are combined with Iron the resultant product is bigger than the Fe2 molecule it replaces. When physically removed from the piece of Iron (or steel), it leaves a pit. Albeit, the pit may be too small to be readily visible...but it is there none the less. The more rust involved...the bigger the pit.
