Pierre, Thanks for the information. I bought a bottle of Quick Shine and am eager to see how it works. I do have a question as to how you clean your brushes. I used an airbrush to apply Future and cleaned it with Windex. However, I think you wrote that Windex did not touch the Quick Shine, so I am a bit reluctant to run it through an airbrush at the moment. I appreciate any information you can provide.
