My cars bodywork is in considerably better shape than my own!
I use two, maybe three products to was myself yet I use about twelve to was my car each week!
This reminds me of the three ladies discussing their husbands over a cup of tea. The first said, "my husband is like a Mercedes, large and comfortable". The second said, mine is like a Porche, small and quick". The third said, mine is like an Austin 7, you start him by hand and jump on while he's going"!!!
