Homebrew PCBs

MG Chemicals has two conductive prints that they claim can be used for  hole plating. Like I said "they claim" :)) ... so no idea if they really work. That's why I am asking first.

One of them is Nickel Print (around 11$ for 3/4oz) and  second is Silver Print (around 35$ for 3/4oz). The difference is in the conductivity, obviously the nickel one being less conductive. MG is saying that they can be used for hole plating. 

I am curious if anyone has tried any these two? If it really works for sure will make life a lot easier for DYI-ers like us. 

I think using first the nickel one to "pre-plate" and then electroplate or just thin plate with liquid tin to make the soldering work better may do the trick ..... I am not talking doing production work, just to get prototyping easier.
