My sister in law’s fiancé owns an oil company; I just detailed his Ram pickup truck. When I delivered it, he asked if I would be interested in detailing his 10 company trucks that deliver the gas to the gas stations. He said that he would have someone wash them I would just have to polish and wax them. He said that he would pay me $300 for each of them. I have two questions, has anyone done one of these before? What is a good product to clean/polish all of the chrome?
