Hi Peter. Rack plating means the parts were hung on hooks. The hook draws current and consequently it will leave "rack marks" like you describe. However, it may well be possible to rack the parts better so that the rack marks are smaller and in a inconspicuous area.

Dear Mr.Peter,

There is nothing to worry.
Just use copper jigs or wires for electrical connections.
That will help you to avoid contact marks.

All the best.
