How to copperplate your 3d prints with copper sulfate

I am really new to this topic and trying to explain my current (second try) copperplating setup.

After trying to sand it with sand paper after the plating process I discovered that scrubbing with a screw driver make a really shiny surface..so next time I'll try to work with a dremel for finishing :P The second lesson I learned is, calculate the mA per cm² more precise. I think I had too less in this video.
Next time there will be a video too, to capture my progress.
Thanks for watching :)
