I worked in my dad's body shop in high school (my hands were often dirtier then the boys) and I worked in my aunt's detailing shop as an adult.
It's hard work, it smells, hard on the back, your hands get cut all the time, in the winter it's cold in the summer it's hot BUT I enjoyed it as well.
It's not for the old, too hard on the body, it's a young person job. Perhaps some day you will open your own shop and have an all female crew. Women would run to you, would as someone else said trust you more. So go for it. Try it and see how it goes. If you don't like it you can perhaps work in the parts department, that is a bit easier.
