These were a set of metal tiger tracks I had and was thinking of using in a project. They were stored for 8 years in a dark box. They were painted at some point.

On picking them up, small bits started to fall off like dandruff. It took a while but the bits were from an area holding the pins. The track function seems OK but it cannot be healthy.

Is this caused by the paint perhaps or something else? I don't know if the tracks are steel bit I doubt it.
