Early Russians were blued. Later Russians were painted (high quality, high temp paint).It's a high probability event, not an iron clad guarantee. Maybe the blanket in this particular case doesn't attract moisture. Maybe the SKS is finished in some rust resistant blue / parkerization / paint. Who knows?
Chinese SKSs, depending on when and where they came from, were blued, painted, or coated with something like parkerizing.
Most others were painted.
The painted SKSs have essentially zero problems with rust, unless the finish gets chipped off. But once it does, if the storage conditions don't improve... the rust spreads like cancer.
