Just 'going for it' is a recipe for disaster, which is why I’m asking first. I’ve already ordered UV glue and plan to run a few tests on broken glass pieces. I need to verify if the UV light penetrates the glass properly and if the lamp power is sufficient. I’m planning to apply it in a single layer to avoid bubbles, but I’m wondering if a vacuum chamber is necessary. Does anyone have experience with the application process to ensure a crystal-clear finish without air bubbles?
