Spray painting is a painting technique in which a device sprays coating material (paint, ink, varnish, etc.) through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles.
Spray guns evolved from airbrushes, and the two are usually distinguished by their size and the size of the spray pattern they produce. Airbrushes are hand-held and used instead of a brush for detailed work such as photo retouching, painting nails, or fine art. Air gun spraying uses generally larger equipment. It is typically used for covering large surfaces with an even coating of liquid. Spray guns can be either automated or hand-held and have interchangeable heads to allow for different spray patterns.
Single color aerosol paint cans are portable and easy to store.
The Metropolitan Borough of Dudley is a metropolitan borough of West Midlands in England. It was created in 1974 following the Local Government Act 1972, through a merger of the existing Dudley County Borough with the municipal boroughs of Stourbridge and Halesowen. The borough borders Sandwell to the east, the city of Birmingham to the south east, Bromsgrove to the south in Worcestershire, South Staffordshire District to the west, and the city of Wolverhampton to the north.
Being a metropolitan borough Dudley is effectively a unitary authority, with the exceptions of Transport for West Midlands, (publicly branded as West Midlands Network), fire and police services, and the local government pension fund (West Midlands Pension Fund), which are jointly run by the seven metropolitan boroughs of the West Midlands county.
For Eurostat purposes, Dudley is a NUTS 3 region (code UKG36), and is one of seven boroughs or unitary districts that comprise the "West Midlands" NUTS 2 region.
