Here is another paint booth that is set up to paint the starter set passenger cars. There is no masking done on these cars. If you look at the metal box around the car with the two handles and a ton of paint globbed on the sides, this is how they cover the areas that do not need painted. The painter puts the car in the vice type device and then sprays the car. When he opens up the vice, he has perfect lines on the car and speeds up the process of painting the car greatly.
