Smaller "Park scarring" can be very easily remove it. For very deep scratches, however it is not suitable. The application is very simple: Apply a polishing cloth and then polish circular on the affected area until the area is dry. Repeat if necessary. Finished! Then, if necessary, apply hard wax (to protect). Even if you wear no gloves (what I consider to be wise after the event), the paste comes with thorough handwashing quite well back down. But you should be careful with the clothes because the paste is quite fluid and easy kleickert.
