The vehicle has now started the paint process. It starts by the paint tech sanding down the entire panel(s) to ensure that the sealer, primer, and paint will bond correctly to the repair material and already-existing paint on the vehicle.
Once the first round of sanding is complete, the vehicle is then masked for sealer and primer. The vehicle is then brought into the paint booth for the sealer and primer to be applied. Then the sealer and primer are baked for a certain amount of time until dry.
When the sealer and primer have completely dried, the vehicle is then brought back out of the booth to sand down again for paint. This ensures that the paint bonds to the sealer, primer, and already-existing paint on the vehicle.
The paint tech will then get the correct color code from the vehicle so that they can mix the paint for the panels that need paint. There are many variants of color codes and each vehicle is different, even if it has the same code on it.
After the paint is mixed, a "spray-out card" is made. This is so that the paint tech can make sure that the color that they have mixed matches the vehicle before actually applying the paint to the vehicle. If something is off, they can fine-tune and tweak the color as needed.
Once the color is matched, the vehicle is brought back into the paint booth and fully masked so that the paint and clear coats can be applied.
The paint tech then applies several coats of paint to ensure full color coverage and even coating. This ensures that the color and paint will have a lasting finish.
The several coats of paint are then baked in the paint booth. Once the paint is dry, the coats of paint are sanded down lightly so that the clear coats can bond successfully to the paints coats.
When the paint coats are sanded down, then several coats of clear are applied to the panel(s). This coat is the one that gives the shiny and brilliant finish to the paint that almost every vehicle has on the road today.
After the paint tech is done applying the clear coats, the vehicle is then baked in the paint booth for the last time so that the clear coats have set enough to be polished. Once dry, the vehicle/panels are removed from the booth and the vehicle is ready to be assembled.
Once the painted panels have completed drying, the vehicle is then reassembled (this also happens during the detail process most of the time because some panels need to be polished first before they can be fully assembled.
