Copper Kettle acrylic craft paint is specially formulated to paint onto pebbles and rocks, and can also be used as a high-quality paint for wood and other craft projects. The paint has excellent coverage and a bright, shiny, metallic finish. It’s water-based and non-toxic and is ready to use straight from the pot. It works very well with dotting. When painting fine detail over a Copper Kettle background, we recommend applying a thin layer of Primer over the metallic paint first.
