Re: Anyone done acid washes?
I think I may have an idea of how to get the silver lines.
Apply the rubber cement WHILE the part is quite wet. Also, apply the bleach just before it is fully set on the sides. The middle part will be protected, the edges may have leakage (which is the desired effect). Let dry. Then the bleach will have enroached and be cemented in so far. Then continue like normal cleaning and dunking in the other dye. It may take some experience knowing the timing of this.
