I just got a set of Prince Albert cranks back from the chromers and the right side arm came out badly.

Basically where the sprocket bolt attaches to the arm, its not sealed at the back so when they are dipped, the chrome / liquid chemicals are able to get inside the arm so after they have been in the bath, the chemicals leak out and cause the right arm to get a matt finish where the liquid leaks out.

any ideas on this?
