Rust on tape heads

Hi
 If the heads themselves have some rust, you need to polish
the heads a little before dragging tapes across it. The rust
pits will have sharp edges on them that will damage the tapes.
You should use a fine polishing compound, like jewelers rouge
or cerium oxide to burnish the edges so they don't do more
damage.
