How to keep dye off of plastic trim?
Iím getting ready to dye a banjo resonator using TransTint dye dissolved in denatured alcohol. The banjo resonator has white plastic trim on the front and back edges. The trim is made of ABS.
Iím keen to keep the dye off of the white plastic trim during multiple dyeing sessions.
Iíve thought of tape, but Iím not convinced that tape will work all that well since the dye is thin and solvent based.
I also considered putting shellac on the plastic trim to protect it, but it seems that the alcohol based dye will at least partially dissolve the shellac making it ineffective.
Any other ideas or advice? Is there a tape that works effectively in this situation?
