Brush plating

I’ve searched the archives and found a little bit about brush
plating but I’m hoping to get more

Does anyone use the JNT Brush Plating and Dip-Coting Kits supplied
by Grobet?

Any advice for someone wanting to plate 24k yellow onto 18k yellow
pieces of approximately 1 inch by 1 inch, one or two pieces at a
time?

Thanks!
Bill
