This single component crackle medium gives a touch of crackle effect to any surface and is a great way to create a cool effect on your lure, Use an acrylic paint on the surface first, once dry apply the crackle medium ( thicker coat = bigger cracks).
Once the crackle medium has dried, paint the surface again with an acrylic paint of a different colour than the original layer. The second layer of paint applied on the crackle medium will start to crack when drying. The base coat applied initially will peek through the resulting cracks.
The pattern of cracks depends on the technique used to apply the paint layers. You can also experiment a little with different application methods too.
