Once I get out of school, I'm starting a job where I detail cars for a rich neighborhood. If you have any tips for me I'd appreciate it. What's the best way to dry it. (towels, where to buy them, etc.) Also, what are the best products to use, that won't cost me a fortune? (I'm trying to make a profit here). I don't miss spots or anything like that, so what would you recommend I charge?
