Can I fix pigment to plastic? Answered
This may be a stupid question, but I'm going to ask it anyway. I bought about $150 worth of candle-making supplies for $5 at an estate sale years ago, but I haven't used any of it for years, due mostly to the fact that I ruined most of the molds before I knew you needed a double-boiler. Oh well. Anyway, amongst all the wax and molds and wick, I got two or three bottles of powdered pigment. I'm now into circuit bending, and now I'm interested in decorating bent instruments. I've worked with paint pens and spray paint, but I thought it might be cool to use the pigment. I don't know how to use it, and I can't find anything about fixing pigment to plastic online.
So, my questions are:
-Do I need to mix it in with glue or some fixative, or does it somehow stick to the plastic?
-If I sand the plastic, will the pigment stick in the wells created?
If nobody can answer, I can probably find a piece of scrap plastic to test it on, but I thought I might try asking here first.
