The Early Years

Aerosol can paint as we know it today was created by Edward Seymour, a paint salesman, who in 1949 added paint to an aerosol can to demonstrate paint to his clients. But the story goes back to 1899, when scientists Hebling and Pertsch developed a pressurized aerosol delivery using gas propellants, which led to the invention of the aerosol can by a Norwegian engineer, Eric Rotheim in 1927. From there, aerosol paint in a can has evolved into a common household item that’s ideal for those that currently hold an automotive career and use it primarily for maintaining and repairing vehicles.


What is Aerosol Paint and how is it Used?

Aerosol paint is stored in a pressurized container and used with a valve that is held to release the paint inside the can. The paint released is a mixture of paint and pressurized gas or compressed air. Each aerosol paint can also contains a stainless steel ball inside that when shaken mixes the paint, which is where the rattling sound comes from. One of the main reasons that it was created and why it is still popular is because aerosol paint can quickly dispense paint across large volumes. Its nozzle also makes it more challenging to evenly apply the paint, as opposed to using a spray gun, even though with enough practice it can be applied uniformly. For that reason, aerosol spray can application in automotive painting is best used for touching up small spots, rather than painting an entire vehicle.

Currently, aerosol cans are found in almost every household. Aerosol paint cans are also very practical in that they can be used for primer, base coat, clear coat and final color with minimal amount of skill, though may initially take some practice. The evolution of these paint cans means that they are used in a variety of applications, many of which are within the automotive industry, has created a market for at-home use that requires little to no specialization, ensuring the long-term popularity of aerosol paint.
