There are a few threads here already explaining why a tour is not possible in Oshawa. As for painting, they are not painted in 'batches'. One car can be painted black, and the next one yellow with no impact.

The robotic paint guns are thoroughly cleaned between each car with a water based solution (color coat is water based). All paint retrieved from the gun during the cleaning process is recycled back into the proper color vats to be used again. The Oshawa paint plant is one of the most advanced plants in North America and all risk has been engineered out of the process.
