Universal All Surface Paint is a durable formula suitable for interior and exterior surfaces. It can be applied directly to many surfaces, including non-ferrous and galvanised metal. For optimal results on metal surfaces, we recommend priming first with Rust-Oleum's Universal Special Metals Primer. If you're dealing with stain blocking, particularly nicotine and tannin bleed, use Rust-Oleum's Universal Stain Block Primer before applying the paint. This advanced brush-applied paint and primer in one is available in a satin white finish, packaged in a 250ml size.
