Dulux Metalshield Multipurpose Spray Paint can be applied to a range of metal and pre-painted surfaces. With a semi-gloss finish, it is ideal for the maintenance of pre-painted gates, fences, gutters, downpipes and roller doors. Use it on metal, steel, wrought iron, galvanised iron, copper, stainless steel, and brass. No primer is required for new bare steel, wrought iron or pre-painted metal surfaces. With a rapid dry time of 30 minutes, your exterior metalwork will be looking as good as new in next to no time. Dune is a Colorbond standard colour – a warm, pale grey associated with the dusty earth of the Australian bushland.
