I get the point on the chromate depleteing the silver and the sedement but what I found was when I first mixed up the bath it did not appear to mix very good and I have only done the 2 small test plates and then tried to do my basket of bolts that only partially blackened I did rinse the basket with distilled water but due to a lack of force from the spray maybe there was still some muratic left from the dip in it.

I think Caswell better improve there instructions my version 9 manual that I just got with there kit does not contain instructions on the black chromate
which when I called tech support on the instructions they said they would have them in the next revision of the manual.
The tech I spoke to told me just to mix it as the black chromate container stated and dip the parts in it, I then ask him to email or fax the instructions to me and was told they hadn't been writen yet. I think that Caswell should replace the product at no charge seeing it was anounced as being new in 2006 as I found out on this forum. The instructions that they issue should also contain some of this information like using sulfuric acid as the muratic is not compatable. Also want to go into the blue chromate after seeing the bolts that you did to prevent the water marking and white rust, what I am plating is for use on my show car and needs to maintain the Cadium and Black oxide appearence on bolts and hardware this is why I bought the kit so I could get the black finish that will last, the oxide will get rust on it just from trailer travel and humidity.
Thanks for all the input.
