Razor Knife

A razor knife is a core tool of skilled hand installation. Working against the frit edge, an experienced installer trims each film panel to follow the exact contour of the glass, producing a precise, flush edge tailored to that specific vehicle.

Hand-cutting to fit is normal, careful craft. A steady technique, the right blade depth, and protection of the surrounding trim let the installer match the film to the glass with no gaps or overhang. Infratint custom-cuts each film by hand to fit the vehicle's exact glass.

The quality of the result comes down to the care and skill behind the blade: a clean, factory-look edge on every panel, finished and checked before the car leaves the bay.
