Universal All Surface Paint is a durable formula designed for interior and exterior surfaces. It's suitable for non-ferrous and galvanised metal, and can be applied directly to many surfaces. For optimal results on metal surfaces, we recommend priming first with Universal Special Metals Primer. If you're dealing with stain blocking, particularly nicotine and tannin bleed, use Universal Stain Block Primer before applying the paint. This advanced brush-applied paint and primer in one is perfect for a variety of projects.
