Stabilizer Ceramic Spray - Ceramic Coating Spray - Ceramic Quick Detailer - SiO2 Sealant - Paint Sealant - Ceramic Waterless Wash Treatment - Silicon Dioxide Spray
- A CERAMIC BASED COATING THAT CAN BE USED ON A CAR WITH OR WITHOUT A CERAMIC COAT - Stabilizer is a Sio2 based spray that can act as a stand alone coating or as a topper for an existing ceramic coat. You do not need to have a ceramic coat on your car in order to use Stabilizer, however if you already have a ceramic coat then you'll quickly notice how this spray enhances your hydrophobic properties and restores depth to your vehicle's appearance.
- SAFE ON ALL EXTERIOR SURFACES - Stabilizer can be used on all of your vehicle's exterior surfaces. You'll love the versatility of being able to protect your paint, wheels, windows, and exterior vinyl. If you have a vinyl wrapped car then Stabilizer is a great option to keep your wrap looking pristine. Another benefit of using Stabilizer is that it also provides hydrophobic protection on your windows, which eliminates the need for purchasing various products to protect your vehicle.
- EASY TO USE - You'll want to wash your car via double bucket method and then decontaminate the paint before you apply Stabilizer. This is the recommended method of preparation before applying Stabilizer to your vehicle.
- HOW TO USE - After washing, decontaminating, and drying the vehicle you will want to apply using a clean microfiber towel. You will need to spray one side of the towel about 4 times, then spray a section on the vehicle, wipe off immediately and then use the dry side of the microfiber to wipe off any potential streaking.
- BETTER PREP EQUALS BETTER RESULTS - Though it is recommended that you wash and decontaminate the surface before application, you can achieve higher quality hydrophobic properties with a longer coating life if you do some sort of paint correction before hand. Eliminating surface defects before applying Stabilizer creates a stronger bond between the clear coat and the spray.
