Should you pre-cut small windows?

Method 1: Precutting is a matter of debate. Some tinters think that you can’t achieve a professional level of quality when precutting compared to trimming on the window. Other tinters believe it’s possible with proper measuring and saves time. Other tinters are somewhere in the middle, and they will line up one or two factory edges before trimming the remaining edges in place. If you’re worried about corners “bunching up” on you, you can try putting small forty-five-degree angle cuts in the corner to help prevent this. If you’re dealing with french panes, paper cutters can be very helpful.
