Aerosol paint

Spray paint (scientific name aerosol paint ) is a type of paint that comes in a sealed pressurized container and is released in a Aerosol spray when depressing a valve button. Spray paint leaves a smooth, evenly coated surface, unlike many traditional rolled or brushed paints. Standard sized cans are lightweight, portable, cheap, and easy to store. Aerosol primer can be applied directly to bare metal and many plastics.

In 1949, Edward Seymour added paint to existing spray can technology at his wife Bonnie's suggestion. It was initially designed to demonstrate an aluminum paint he developed.

Most aerosol paints also have a metal, glass or plastic ball called a pea inside of the can, which is used to mix the paint when the can is shaken.

Acrylic-based craft primers and vinyl dye can be used on plastics like models or miniatures.

Most brands include a wide variety of paints, including primers, heat and traffic resistant enamels, gloss and matte finishes, metallic colors, and textured paints for home decor.

Aerosol paint is useful for quick, semi-permanent marking on construction and surveying sites. Inverted cans for street, utility or field marking can be used upside-down with an extension pole. APWA (American Public Works Association) has standardized colors for utility and excavation markings. Hiking trails can also be marked with aerosol paint trail blazes.

Small to medium-sized repairs to automobile bodywork can be completed by enthusiasts at home using aerosol paint, though to paint an entire vehicle in this manner would be difficult and expensive. The main disadvantages, compared to a professional spray gun, include the limited quality provided by the built-in nozzle and the lack of infrared baking after applying the paint, which indicates that the paint could take several months to obtain its final hardness.

Plasti Dip is a brand of aerosol paint that hardens into a rubber-like layer that peels off relatively easily. It can be used on almost any hard, clean surface without prior sanding. Plasti Dip is sometimes used to decorate or protect cars, because it can be sprayed over the existing paint and removed anytime.
