Step-by-step instructions

Roof Panel Cleaning
Clean entire roof panel including sunroof edges, antenna base, and rain gutters. Remove any wax or sealants. Dry thoroughly.
Pro tip: Use a step ladder or stool for comfortable reach. Never lean across the roof, as you may drag contaminants.

Alignment Reference Lines
Use masking tape to create centerline from windshield to rear window. Measure equal distances from roof edges to ensure centered placement.
Pro tip: The roof panel seam or sunroof edges make excellent alignment references.

Two-Person Application
Roof graphics require two people. One person holds the graphic in position while the other applies. Use the hinge method for large graphics.
Pro tip: Communicate clearly with your helper. Establish hand signals before starting since you'll be on opposite sides of the vehicle.

Progressive Application
Starting from the centerline, squeegee outward toward roof edges. Work in 12-inch sections, maintaining even pressure throughout.
Pro tip: Roof graphics are visible from above, so bubbles are more noticeable. Take your time to squeegee thoroughly.

Complex Contour Work
Use heat generously on roof curves and transitions. The roof has subtle compound curves that require vinyl to stretch slightly. Heat makes this possible.
Pro tip: Heat to 150-180°F for curves. The vinyl should be warm and pliable but not hot enough to distort.

Edge Trimming and Sealing
Trim excess vinyl along roof edges using a sharp knife. Apply final post-heat to all edges and seams for maximum adhesion.
Pro tip: Leave 1-2mm overhang on edges if possible, then wrap and tuck using heat and pressure.
