Thanks gents. It looks like I may guilty on several fronts. David, your pictures speak volumes! That is precisely the effect I am trying to achieve. I think I shall begin with clean metal and start the process over.
I may have applied the rusting solution too heavy and gotten a lot of overlap. I am using a cotton swab and it seems to work well.
I am using Laurel Mountain rusting solution and Radio Shack's PC board etchant. The effects are right on. It's just the technique that needs refining, I think.
