Rubber Protection Film
The protective film is designed to extend the life of the rubber and maintain the tackiness of the rubber.
After each game, clean the rubber with cleaner, place the protective film on it and use a roller to press it to the rubber to expel the air between the protective film and the rubber. If you take care of your rubber this way, you will maintain its tackiness throughout its lifetime and thus also its outstanding properties.
When removing the protective film before a game, remove the film carefully so that it does not break, as it sticks to the rubber quite tightly.
