Here's my baby. Over a year since any correction was done, and strictly ONR washed CAREFULLY in that time. I love the stuff, couldn't live without it.
I use ONR occasionally. It really depends how dirty the car is. If your car is daily driven and covered in dirt, mud and/or bugs, you can not ONR. Even with ONR pre-soak, it will mar the surface.
