To use these tail light overlays, first clean the application and surrounding areas. You can use a microfiber cloth and a detailing spray or glass cleaner. Make sure there's no wax on the lens. We suggest using a soapy water solution (StickerFab Application Fluid is recommended). Wet the back of the vinyl with a bit of dish soap in water, so you can slide it into the right position easily. Once it's in place, use your fingers to push out the soapy water. You can use a heat gun or hair dryer on low heat to dry the vinyl faster. For now, refer to our BRZ installation guide. As for maintenance, keep the overlays clean by gently wiping them with a soft cloth. Avoid using abrasive cleaners that could scratch the surface.
