That's normal on all painted Stern lockbars. They masked off the latch area before paint/powder, and it's exposed steel that then oxidizes. Doesn't hurt anything, but if it bugs you just put some blue tape on and hit the rust with steel wool.
Quoted from P1nhead:Pics of the crap powder coating job... some build-up and pooling of material on the lockdown bar as well, made the radius too large for the round over on the cabinet and started to damage the cabinet - very noticable when looking at the machine.
Stern has not responded all week and my distro says open the ticket first with stern then they will be able to take care of things.
