## Background
BACKGROUND
This disclosure relates to an improved mobile paint booth system and method for applying paint to a vehicle.
When used car dealerships purchase used automobiles, often the used automobile has basic wear and tear such as scratches. A low cost solution to this problem is to apply paint to a car, however due to environmental and other concerns, the paint must be applied in an enclosed space. Larger dealerships with an expansive fleet often have an enclosed space on their lot dedicated to making such repairs. However, smaller lots with smaller resources often do not have such facilities. Instead, they must send each car to an outside facility. However, such process puts mileage on the car, increases the time that the car must be away from the lot, requires additional man-hours moving the car, and therefore makes the process of applying the paint more expensive. As such it would be useful to have an improved mobile paint booth system and method for applying paint to a vehicle.

Entry port 300 can be opened by unfastening zip fastener 302 from second wall 204. Mat 304 can be used as a cover to protect entry port 300 as automobile 901 is maneuvered into interior space 105.
FIG. 9E illustrates automobile 901 within mobile paint booth 100. Once automobile 901 is positioned within interior space 105, entry port 300 can be sealed again to protect interior space 105 from being exposed to contaminants that are present in exterior space 106. Thus, zip fastener 302 can be used to bind entry port 300 with second wall 204, completely sealing interior space 105 from exterior space 106. In an embodiment wherein entry port 300 can comprise first door 303a, workers or the driver of automobile 901 can use first door 303a to enter and/or exit from mobile paint booth 100.
FIG. 9F illustrates external view of first wall 203 comprising second door 303b and orifices 501. In such structure, workers can also access second door 303b from first wall 203. As such, doors 303 can also be fastened back in place through zip fastener 302 after workers enter and/or exit mobile paint booth 100. This is to ensure that interior space 105 is sealed from the particulates in exterior space 106. Furthermore, air pressured device such as a hose can be inserted within mobile paint booth 100 through orifices 501 in first wall 203.
FIG. 9G illustrates emergency exit 700 in one of wall section 104. In a scenario wherein workers need to exit out from mobile paint booth 100 immediately, the workers within interior space 105 can pull quick-pull handle 702 to open emergency exit 700 from wall section 104. Since emergency exit 700 can be connected to wall section 104 through a hook and loop fastener, a quick pull on emergency exit 700 can expose opening 701, allowing workers to easily get out from mobile paint booth 100.
