Smart Strip Advanced Paint Remover strips multiple layers of acrylic, latex, oil, and water-based paints, varnishes, and stains from most wood, metal, and masonry surfaces, usually in a single application. This versatile paint remover works effectively indoors and out. Unlike many other paint removers, the Smart Strip Advanced gel formula is completely non-caustic. It does not contain dangerous or hazardous chemicals like methylene chloride or NMP. BOV comes in a spray can powered by compressed air. This makes the product safer, easier to use, and cuts down on waste.
