Homebrew PCBs

Dave,

I used that method with scratch and etch consept developed by Jojn 
Kleinbauer from www.kleinbauer.com

I used that paint in a spray can and I noticed that it is etch 
resistant... to a degree. If left for too long my HCl based solved 
lifted the paint but for regular times it etched nicely.  Mike
