Color Magic no-fire paint can be used on metal, glass and other surfaces. Unlike water based pains, Color Magic is unique in its durability, versatility, vividness and wide range of opaques, transparents, and metallics. Paint can be applied with the included brush, sponged on, airbrushed or used with an eyedropper. Paints are available in a variety of colors and finishes. This paint comes in a 1/2 ounce bottle with a brush cap, just like fingernail polish. Please click on "Detailed Description" to see Frequently Asked Questions about this product.
