Plastic scraper 10 cm for bubble-free bonding of window films on glass surfaces. Can also be used to apply grounding straps. Water and bubbles can be pressed out with the smooth edges without scratching the foil.
Left side: The film was applied dry by hand to the window pane -> Air bubbles.
Right side: Wet bonding with mounting concentrate FMK30 and scraper FVR10 -> NO air bubbles!
