The passivate is a chromate conversion coating that, when diluted is enough to make 10 litres and used as a dip coating. The part should be very well rinsed after plating and then dipped in the dry acid solution or dilute HCL for a few seconds until the part fizzes all over, before a good rinse. Then the part sould be dipped the passivate tank. While it is being dipped the items should be moved around and left in for the right amount of time or until the colour you want has been achieved.
