Apply to the rear window or body of the car at room temperature after removing dust and oil. -----------The following are the unedited comments from repeat customers: My colleagues and friends at work compliment me a lot! They ask me where I bought it, so I recommend it without permission (sorry!). DR recorder stickers are often small, hard to see even when applied, and difficult to see at night, so I'm really happy with this perfect product♪ As a female driver, I often get tailgated or looked down upon, but that hasn't happened since I applied this. Thank you very much♪
