Frank, it's perfectly plausible.  Machinists use the principle for
fine fitting/sizing of parts, using a tool called a lap which is made
of a soft material (often copper) charged with abrasive.  Rust
particles and road sand are perfectly valid abrasives for steel, and
there could also be fretting corrosion occurring.
