Does the invisible license plate spray actually work against camera flashes?

Based on testing with an iPhone flash, the invisible license plate spray does not appear to be effective. The product tester concluded that the spray fails to obscure license plate visibility as promised when exposed to camera flashes. While they acknowledge that speed camera flashes might be different from smartphone flashes, the initial test results were not promising. After evaluation, the tester definitively labeled the product as a scam, suggesting consumers should be wary of its claimed ability to prevent license plates from being captured by cameras.
