I hate to put a kebash on the liquid spray waxes, but they tend to be hard on the finishes, more so than regular waxes. The carnuba wax is better.

Now I am not familiar with "petrol green." Is the color metallic, or is it is a solid color. Metallic means is there shiny, silver like flakes in the finish. If it is a solid color, there probably is not a clearcoat on the car. It may be what is called a monocoat. In that case, the car may need to be rubbed out.

Can you take a picture of the problem areas and post them?
