Dear Daniel,
Good Day to you!
Firstly, we would like to declare the coating which we used for M4.8X19, M4.8X25 & M4.8X35 were all Ruspert coating.
ViridAct is one of the component, and it was belong to Ruspert.
Our coating production of these screw was
Base zinc Plating-the first layer
Ruspert coating-the second and third layer.
Secondly, till now, after we send the samples for re-testing, it already 430hrs passed, and we also did the third-testing( samples received from you)-it already 164hrs passed,
and both of them did not have any red rust occurred.
James told us that he will sent the samples to another testing Lab for re-testing after his visit on 10/4, but it seems there is no progress of this matter.
For any comments, pls let me know.
