After the Parts have been Coppered, you should add the Promoter:
Add 5.0 ounces 142 grams of High Efficiency Promoter
Allow 1-2 minutes for the Promoter to disperse in the barrel.

Load 500 pounds of Oil-Free Pins and Media to the Barrel
Adjust Water Level and Water Temperature to 70° to 75° F.

Next, Add 3.8 ounces 106 grams of Zinc Dust
Allow the Parts to achieve a silvery hue.  If they do not, add, in sequence, more Promoter and Zinc Dust.

You should make  15 adds of Zinc Dust, each consisting of:
Add   1.11 pounds 18 ounces of  Zinc Dust

or
675.5 grams of  Zinc Dust
Add   0.8 ounces 24 grams of  Continuation Promoter
Allow  2 minutes and 0 seconds between adds.
Allow the metal to plate out for 10 minutes after the last additional of metal, keeping the pH below 2.  You may wish to water-polish during this part of the cycle.
