Ok, the nickel plating is getting better...

After several tries with several things, the plating is going better. Still not quite there, but...better.

What I am trying to plate is guitar parts made from nickel-silver.
Here are a couple pictures..

In this one, you'll nice a slight wavy line on the right hand side of the object, starting on the bottom edge and moving upward toward the hole on the right. What causes this? Power was not interupted.
There is also a small dimple in the plate, but it is hidden in the glare.

Before plating, the part was polished to a mirror shine. I used to be a master polisher in the knifemaker's guilde, so I know how to polish well. Polishing is one of my favourite things to do....
Yes, I used the degreaser.
I'm pretty sure I'm got the amperage set right at 1.2. Part is 2.74 x 1.49 x .625. The holes are .214 dia, and the part is open on the rear, so both sides get plated. - 18.5 sq inch without subtracting the holes?

There is also a light haze, (disregard the buffing haze) as is shown on the left of the glare near the bottom. Manual says excess Hydrogen Peroxide. But, this was happening before I added any to cure the pitting problems...and I only added a tiny bit, at that.



The plating is every so slighty rough to the touch, like tiny particles of sandpaper had been lightly dispered onto it.

While I've got you here, does anyone know what sort of chemicals and process can be use to re-create this effect?

I have to assume that it was something sprayed onto the part through a rack set up to disperse the spray in only the corroded areas. I've tried muriatic acid - fuming can be used - but it doesn't turn brownish and is extremely difficult to control.
