I am usually interested to topics related to soft plastic baits and in this Forum I found really good informations.
So, to repay your good suggestions, I would like to share with you a really simple technique about painting hard baits with Nail Art Powder. Perhaps some of you already know such technique, then it could be intersting to compare our experiences.
Years ago I stopped to pour my cranks in epoxy resin ... the cheap chinese blank are really more convenient.
In Nail Art Powders you can find all sorts of pigments: pearls as the marble mica, metallic as silver and gold, iridescent colors as the showed green/violet.
The technique to apply the fantastic nail art powder to our blanks, is exacly carry out from same Nail Art application: we need a dark background, as a sprayed black (by a can for instance); a gloss substrate, as the sprayed Plastidip in our case, and after 5 minutes, when the sprayed plastic is not more tacky, you can apply the powder that you prefer with a brush or the Nail Art spongy tool.
Talking about the back or belly colors, you can surely use another kind of powder, but I found that powdered surface is a good base to spray other kind of colors. Even if I sometimes use the airbrushing pen, in this case is really easyier to brush a little bit of color from a Copic marker with the Spritzer pump (ndr Spritzer is a handy pump where you attach the marker pen, obtaining a sort of airbrushing effect, let try to search it on the net).
Last step is simply to seal off all, glued eyes included, with another Plastidip spraying.
