I too have the "CopyCad & Zinc Blackener, New Formula". The bottle labels says mix at 9:1, but apparently this is not correct, it should be mixed at 4:1. If you're mixing at 9:1, then the solution is too weak.
It would seem that the earlier printed manuals, and bottle labels, are incorrect. |
Ahhhhh. I too have New Formula Blackener, and the label and Version 7 of the Manual both state a 9:1 ratio.
I called Caswell, and they are sending another bottle of Blackener to me, and to make things right for the mix-up and time lost with the weak solution, they are also sending me another zinc plate and more zinc solution...stand up business ethics
I hope to have the black problem beat with the new concentration, and then it only leaves getting the yellow chromate to be as durable as I can get it for the cad look parts.
SeanC, thank you very much for the help! I had read your thread about the possible bad electrolyte completely, while waiting on my kit to arrive, and it made me edgy about the power supply ability.
Next time I plate something (hopefully tonight, I'm trying to get an 86 GTI back on the road) I will make note of the amps and volts. Thanks again!
