Homebrew PCBs

I need to get some PCBs done, no matter if the tank is ready or not, so i  
had a chance to do some more experimenting.

The neutral silicone does not work well at all.
The printout is all flaky.
Also, it does not feel as tacky to the touch as the well working acetic  
silicone i tried before.
I do not know exactly what the problem is, currently a few sheets of paper  
with the acetic silicone are curing for direct comparision.

Maybe another brand of neutral silicone would be better, or maybe the acid  
would not cause any harm to the printer, or maybe it could be washed off,  
or maybe the problem is something else entirely.

I will let you know what i find out.
