Hi Chris,
Thanks for taking the time to write this.
We do not rate any of our boards to be water-resistant or waterproof as riding any type of skateboard in wet conditions, whether electric or not, is very dangerous.
In the GTR Range, we have made every effort we can to protect the electrical components from foreign substances and materials. We have a dust seal that runs the perimeter of the casing which has been tested in a water chamber and revealed that no water penetrated the casing. The seals on the boards are dependent on the correct installation process and as such, sealing abilities can vary. Even though we have taken this extra effort, the boards are not waterproof and water damage is not covered under warranty.

This seal is only compatible with our GTR Boards, if you want additional protection, perhaps it's time for an upgrade 😃
If you have any further questions, please don't hesitate to get in touch.
Cheers
