AK Interactive’s acrylic chipping fluids are odorless, and they are effective in replacing the hairspray technique, and adding wear and scratch effects on our models. First, paint the model with a dark color or the color that you want to see under the scratches. Then apply the chipping fluid directly from an airbrush giving a generous coat to the model. Afterwards, apply your top coat. Lastly, dampen the surface using a brush and water. Use either the same brush or a sharp tool to clear away your top coat to expose the underlying color./n/n35ml
