I purchased the kit in hopes of an easy sign system when I’m on the road for events with the F1 and or F1 Ultra. I found it very easy to etch the glass but found the directions slightly lacking in a few areas. After watching a few YouTube videos, combining best practices, there are a few tips. 1. Cut text in reverse (mirror) as when you install in projector, it will flip the image. 2. Install with reflective side towards the light source. 3. Clean well after cutting and before install with alcohol so there are no hotspots. 4. When removing the rear of the case, twist gently as the fins will bent easily. Ultimately, this kit levels up your being seen at events and for the investment, well worth the expenditure! FlashCraft, LLC.
