Acrylic artist paint for spots and stripes
Believe it or not, acrylic paint sold in tubes works great for soft plastic lures. To adhere better to old plastic (not recently poured within a year), I rub some acetone on the lure's surface, let dry and paint my lures with acrylic paint, straight from the tube, not thinned with water. The paint doesn't come off!
Spike-It Chunk Paint is expensive and has a limited shelf life. It starts to glob after a year or two and the company won't tell you how to thin it. Lurecraft paint and dips are worse because of a bad seal on the bottles they come in.
Try it.
(note: if you use Spike It paint that's starting to glob up, use some PVC pipe prep to mix on some aluminum foil. It has worked for me.)
