A year is a long time for for body and paint but it depends a lot on the shop, their work load, how much is being done to the car and tons of other variables. Sounds like you are a few steps ahead of me as far as body work and the undercoat. These guys had the panels off and on so much between the metal work, blocking and painting to get the panel gaps right it didn't take them long to do the final assembly.
