Re: [MW:27442] What is this defect

 Premature rust
 Low film thickness
 Low DFT
 Here like a deposit from grinding or grid in contact with water get rust
 Can be deposit of grid particles or from grinding or any other types of particle contain iron, stays on flat surfaces and in contact with water rust
