I nornally charge my customers for normal details, pending on type of vehicle. As I have a basic idea how long it will take. But when a customer simply wants their car buffed out and paint correction, should I just charge by the hour? and how much per hour should I be charging? I am not "a professional detailer", but simply do some small time detailing from my home. So I know I shouldnt be charging as much as a prof. detailer would, but I also dont want to under sell my self either.
