The temporary tariffs of 8â30% were originally scheduled to remain in effect until 2005. They were imposed to give U.S. steel makers protection from what a U.S. probe determined was a detrimental surge in steel imports. More than 30 steel makers had declared bankruptcy in recent years. Steel producers had originally sought up to a 40% tariff. Canada and Mexico were exempt from the tariffs because of penalties the United States would face under the North American Free Trade Agreement (NAFTA).
When buying paints for airbrushing purposes, one should buy the paint specifically formulated for a certain purpose, such as nail art or automotive painting, because these are designed with specific properties in mind.
For emulsion paint, just use soap and water for the brushes, rinse them under clean, warm water and pat dry with a paper towel. For oil paints use white spirit to rinse the brushes through and then press them dry with paper towels. For any hardened paint, try dipping the brush in paint remover to soften it.
