[TowerTalk] How do you get a good looking trace when etching?

[Roger (K8RI) on TT]

Over the years I've tried etching boards with various methods. I have 
never gotten a good looking trace. Whether the trace area is cleaned and 
painted on, or photo sensitive, the edges are always irregular.  They 
are not straight and taper to a thin edge. Just what you don't want.

Temp, chemicals (Typically Ferric Chloride IIRC), chemical dilution, 
agitation: All according to directions with the same results.  I finally 
gave up.
