I'd like to start doing some detailing work on the side. To be more specific, I'd just like to do interior and exterior cleaning and some minor paint correction with a PC or Flex 3401. I don't want to get into anything more involved than that. However, should I have business insurance before I start touching other people's cars? What I wonder about is if it'll worth doing this on the side if I have to start carrying business insurance. I'm only talking about doing a couple of cars per month because I already have a full-time job and don't have the time to put into anything more than a couple of cars per month. What do you guys think?
