The protection system will last a considerable amount of time. There is no concrete answer to how long exactly as there are various factors that will influence the longevity of the protection. Below is a list of just a few factors:
• How frequently the vehicle is used
• How frequently the vehicle is washed
• What products are used when washing
• Where the vehicle is parked/stored
• The climate also is a factor, whether the vehicle is subjected to wind/rain/snow/salty roads etc
On average the protection will last approximately 6 months. However, it does depend on the factors mentioned above.
