No, never drive or operate a vehicle with the Bumperninja attached. Doing so is dangerous and may result in damage to the vehicle or product. Always return the product to vehicle’s trunk prior to driving. Please read product disclaimer and all instructions before using.
Yes, our product is composed of EVA Foam, a waterproof material renowned for its ability to withstand extreme temperatures. The Bumper Ninja is designed for outdoor parking. It may also be used in indoor and valet parking garages.
While the Bumper Ninja is designed to offer bumper finish protection, it cannot guarantee complete bumper protection against impacts greater than 1MPH. This product is aimed at minimizing the likelihood of scratches and mitigating the consequences of low impact parking maneuvers. However, it's vital to note that the Bumper Ninja does not enhance a vehicle's crashworthiness or ensure occupant safety in rear-end collisions.
With few exceptions, the product is suitable for most vehicles. It's important to note that rear engine vehicles are not compatible. Additionally, it's advised to avoid placing straps in the engine compartment to prevent any potential damage or injury.
For maximum longevity of the Bumper Ninja, it is recommended to keep it flat in your car's trunk when not being utilized. Folding the bumper should be avoided to prevent any potential creases on the rubber surface.

To avoid any potential damage to your vehicle and the Bumper Ninja, never enter a car wash with the product outside your vehicle. If you prefer to have the car wash attendant handle the task, kindly request them to securely place the Bumper Ninjainside the trunk before they proceed with washing your vehicle.
To maintain the cleanliness of your Bumper Ninja, it is important to clean it regularly. Start by cleaning and washing the back side of the product. Don't forget to regularly clean the rear bumper surface as well to ensure that both the Bumper Ninja and the rear bumper remain free of dirt and debris. You can use a mild soap and water for cleaning purposes. Another option is to use a damp towel or a super soft carwash brush for this task.
In situations where the Velcro on the straps does not adhere properly to certain carpet types, it is advised to make use of the extra 2 Velcro tabs that are included. Attach these optional Velcro stickers to a clean and smooth hard metal or plastic surface underneath the trunk carpet or any other accessible area. Doing so will enable you to securely fasten the ends of the straps to these additional Velcro stickers. Remember, it is crucial not to directly attach these stickers onto the trunk carpeting. They should only be affixed to a clean and smooth hard metal or plastic surface.
