[MW:25743] RE: 25727] MPI on painted joint

My experience is that it does not work,  and this is not surprising. I have had eddy current testing used over painted surfaces to detect underlying cracks with good results, in that cracks were reliably detected. You would need to trial it with coatings on the calibration block.
