I need a VERY fine pen (nothing too much over .25mm) that is water proof and doesn’t smudge, for drawing designs on polymer clay and apoxie sculptures that have been painted with acrylics. I am having terrible luck finding anything. I need the colors black, red, and brown. Any suggestion?
Forgot to add, I will be painting over the sculptures with Liquidex gloss and satin varnish. I don’t want an ink that will smudge everywhere when I paint the liquidex over it! I have been trying to use Micron pens (SUPPOSED to be waterproof and smear-proof), but am having serious doubts as to whether they will work. I did some ink work on one of the acrylic-painted pieces yesterday. I let it sit for 24 hours so the ink could dry, but it still smeared when I rubbed it!
I also need suggestions as to what I could use to protect outdoor acrylic-painted crafts from fading in the sun.
