Does-acrylic-paint-stay-on-metal, acrylic paint is a versatile paint, which is most commonly used in artistic painting, but is also used for more practical purposes such as model painting and painting metalwork. acrylic paint is often used because it is fast-drying, hard-wearing and it keeps its color well, even when exposed to the elements.. Metal surfaces can be painted with various types of paints depending on the type of metal, but if it is an aluminum surface, then a water-based acrylic paint should be used. copper and bronze surfaces use oil or acrylic paints. aluminum surfaces tend to have to be scrubbed with an abrasive pad before they are coated., for metals (with the exception of good-quality stainless steel) you'd probably be best priming them initially with a dedicated primer because acrylics are very alkaline and over time it's likely they could initiate reactions with the metal surface but again how long you want things to last might play a part - just cleaning the surface of a metal with soap and water and slapping on a few layers of acrylic 'gesso' will probably make quite a stable painting.
