if you go to a dealer with no experience dont be surprised if they have you doing all the shit jobs until you get the steps down of how to really detail/clean a car. i have a shop in st pete where i am lucky enough to work on alot of exotics and thats where i started 10 years ago. it sucks at first, but it gives you time to observe the other detailers there that have experience and learn from them, also givin you time to find out which ones know what they are doin and which ones should never pick up a rag. car washes such as grand prix and pelican are good places to start out at. they will work with your school schedule and theres alot of cars that come through so you can learn what you can and cant do on different models. good luck!
