The paint booth is arguably one of the most prominent tools in the impact revamp paint agency. While the spray booth was to start with modernized to keep adverse overspray contained and away from other workers in the shop, it has changed into a tool that not only protects workers but also cuts down on contamination of the surroundings, keeps work unadulterated, and speeds up applying and curing - thus multiplying shop production. The booth has modernized over the years from just a box to paint in to a self-contained painting environment, one that controls airflow, lighting and climate, and controls dirt infiltration. There are connected mixing rooms and vestibules, and there is even talk of paint booths that regulate or eliminate VOC emissions. Though a considerable investment, a properly maintained and adeptly operated paint booth can produce 10 or more paint jobs per day. Paint booth technology has changed as paint has developed, and paint booth manufacturers have modernized contraptions to meet current needs. Some of the first booths used when lacquer was the primary coating were the crossdraft type, generally a simple non-insulated box that had filters at both ends and mainly worked by drawing air in from the rear and exhausting it at the front. Booths of this type worked fundamentally to contain overspray and exhaust it to the outside. Lacquer paint dried mainly through evaporation, and a crossdraft booth helped speed up the curing time, though evaporation time before the paint could be buffed (necessary with lacquer paint) was almost always 18 to 24 hours. These booths were a significant restoration over spraying vehicles in the shop, and they protected workers outside the spray area from overspray. Crossdraft booths had some significant errors. They drew in voluminous amounts of air through the rear door, which in the wintertime could substantially lower the shop's temperature and tax the building's heating capability. They also drew enormous amounts of air, contaminated with shop debris, across un-cured paint, oftentimes depositing dirt as the filters become filled. Filter technology at this time was crude at best, drawing air through paper arresters (filters). The openings in these paper filters were offset causing the air to alter direction and depositing paint mist on the paper as it passed by. Nearly all paint fumes were exhausted out the paint stack. As incoming air rapidly contaminated the rear booth filters, it granted most of the dirt and debris to pass through into the booth. All vehicles painted with lacquer were polished at the time to create the desired shine so small dirt particles were eliminated during the polishing. The next type of booth that was changed was the semi-downdraft booth. In these booths, air was drawn in from outside, heated as needed and entered the booth through the top at the rear, drawing it down over the vehicle and exhausting it out the front at or near the floor. These booths were an bettering over the primitive crossdraft booth because of their ability to heat air while not contaminating the vehicle with shop dirt. Filter technology also was changing. Newer filters passed air through fiberglass that got progressively finer textured, filtering out much more than paper arresters were ever capable of. Incoming air was cleaned with a pre-filtering and then passed through the ceiling filters, providing much cleaner air in the paint area. The air still traveled from the top rear, passing over the entire vehicle to be exhausted out the lower front, and if any dirt did get in or if there was a leak in the booth, dirt was still drawn over the vehicle, depositing it on fresh paint as it passed by.

The paint booth is arguably one of the most prominent tools in the accident repair paint area. While the spray booth was in the first place changed to keep harmful overspray controlled and away from other workers in the shop, it has changed into a tool that not only protects workers but also cuts down on contamination of the environment, keeps work uncontaminated, and speeds up applying and curing - thus expanding shop production.
