[TheForge] Etching Damascus

[Washington, Aubrey O.]

Okay, I know you guys are gonna say, "This boy hasn't been paying attention all these year!"  But, here goes.  I just finish my first pattern welded blade and I'm ready to treat it to make the pattern stand out.   Here are my questions:
 
What is the name of the circuit board etchant one can buy at Radio Shack?
What is the procedure for using this stuff on a blade?  (Straight up or diluted?  How long?  How or if to neutralize?)
 
I know all of these questions have been answered many times.  But I wasn't paying attention because I hadn't made my first blade yet.  Sheech!
