Working plated through holes

The experiment was a success, at least I know it worked on holes down to 1mm. I dont know about smaller holes because I cant see inside them so therefore I will electrically test those soon. But the bigger holes had a nice layer of copper in them which is fantastic. TO proove that it was copper I placed the PCB in tinning solution to see if the holes inside changed colour, and they did!
The resistance of the board (top to bottom), was 0 ohms which is fantastic.

Lets hope that through holes will be something available in my PCB process!

Just checked the 0.6mm holes, they have 0 ohm resistance!!!!
