Hi there,

I am having the same problems with my plating processes, especially white stain. Have you came up with the solution to prevent this issue from happening?

Best regards,

(Full name next time, please, Charn; this isn't an anonymous service). Plating is very complex, and it would take a whole finishing library to describe the most likely causes for a wide variety of defects across a number of finishing processes. But Larry Durney's "Trouble In Your Tank" is perhaps the shortest route to those answers. Good luck.
