JWF, Final Trim

Use A Button

Here we will talk about using a button to make your final trim. This is a great technique to avoid scratching the window. It's a method more commonly used in auto tinting, but can easily be applied for flat glass installations. Please follow these steps below if using a button on the final trim.

1) Once your rough-cut pattern is anchored in place on the glass, take a button from an old shirt and place it between the glass and film. Place the tip of your knife thru the film and into the button.

2) Now that your knife tip is through the film and into the button, carefully drag the button with your knife tip around the window making the final trim.
