Your visor misses the top few inches of glass. That is where low sun gets in, twice a day. A strip of matte vinyl up there closes the gap.

Our matte black visor sun strip for the front windshield shades that band without touching your view of the road. Cut it to fit, stick it on wet, keep it off the camera's view.

Why the glare lives at the top of the glass

Low sun arrives at a shallow angle. It slips over the visor's edge, right into your line to the road.

The visor sits low on purpose, so it cannot block those top inches. Tinting the whole windshield is not an option either.

Most states allow one accessory up top: a non-reflective band above the AS-1 line. That line is the etched mark on your glass, and it sets the band limit.

The product, exactly as specified

This is a cut-vinyl decal: one length of matte black vinyl with transfer tape on the face. You trim it, then set it on the glass with soap, water, and a squeegee.

Two spec lines drive the job.

• Trim-to-fit: 60 inches covers a compact car, a full-size truck, or most van glass. The 10 inch height lets you cut to your state's band height.
• Matte black: not a styling choice. Windshield rules target reflective finishes, so flat black matches the letter of the rule.

That is why this strip is matte while the gloss black vinyl wrap roll in the same catalog is for painted panels, where shine is the point.

What the strip does, and what it does not

It cuts glare, full stop. The vinyl absorbs the low-angle light that blinds you, and the effect is immediate.

It does not cool the cabin. Infrared passes through the rest of the glass, so a band over a fraction of the windshield moves no thermometer. Heat is a job for ceramic window film.

• The 60 in x 10 in black sun visor decal strip is the same size class in PVC decal construction.
• The matte black 12 in x 72 in tint film for lights and fog lamps covers the smoked-lens side.
• Rule for every panel: matte over gloss facing other drivers, and measure the legal line before you cut.

The legal band: the AS-1 line and your state

Find the AS-1 line before you cut anything. It usually sits five to six inches below the top edge, and your state borrows it to set the band depth.

• Marked glass: the etched line is your boundary and beats any general number.
• No marking: use your state's fixed depth from the top edge, usually four to six inches.
• Shallow and plain: end above the line with margin, solid black, no lettering, no color.
• Non-reflective: matte black is the canonical choice. Red and amber read as emergency lighting and are widely banned.

Exceptions exist: a few states allow no band, and some add a light-transmission minimum. Rules change, so read your state's current vehicle code before you cut.

The ADAS camera zone: where the strip must stop

ADAS (advanced driver assistance systems) covers lane keeping, automatic emergency braking, and automatic high beams. Their forward camera sits behind the mirror, inside the band area on many models. One rule follows: no vinyl over the camera's view.

The failure mode is distortion, not darkness. An edge, bubble, or lifted corner acts as a lens and bends the image the camera depends on. The result: drifting lane keeping, false braking, or a recalibration warning.

• Mark first: tape the glass at the top edge of the camera housing, then mark the AS-1 line at the same points.
• Notch or split: lay the band in two runs, or notch it, so the vinyl stops short of the housing. Straight cut lines look deliberate.
• Never run vinyl behind the mirror just because it is "out of sight." The camera's view and yours differ.

Wet installation, step by step

Cut vinyl goes onto glass wet. Soap and water let you slide the strip square after it touches the glass, and a squeegee pushes air and water out.

Your tools: spray bottle, a drop of dish soap, a squeegee, a fresh blade, masking tape, isopropyl alcohol, cloths. Work in the shade on cool glass. Heat flashes the water off, and glass below about 50°F makes the adhesive sluggish.

1. Decontaminate the band. Wipe with isopropyl alcohol until a fresh cloth comes away clean. Wax and road film kill adhesion.
2. Mark the three boundaries. Tape tabs outside the glass at the AS-1 line, the camera housing's top edge, and the wiper sweep.
3. Trim before it touches the glass. Cut the length to your glass width, then cut the height to end above the AS-1 line.
4. Plan the camera cutout. If the housing sits inside the band, mark the notch on the liner side. Two runs with a gap beat one across the lens path.
5. Mix the slip solution. Water with one small drop of dish soap — barely slick, not foamy.
6. Position with a tape hinge. Lay the strip in place dry, level it to your marks, and tape the center.
7. Wet the glass, then the adhesive. Lift on the hinge, spray generously, peel the liner, and lower the strip.
8. Squeegee from the center outward. Firm, overlapping strokes, face kept wet so it does not drag.
9. Peel the application tape. Pull it back on itself at a sharp angle while holding the vinyl down. If a section lifts, re-squeegee.
10. Finish and cure. A final towel pass pulls out the last water. Trim the A-pillar overlap, then keep the wipers off and the car dry for 24 to 48 hours.

The same sequence works on any exterior vinyl. The exterior body kit installation guide follows the same logic: clean surfaces, test-fit, cure window.

Living with an exterior strip

The band mounts on the outside of the glass. An inside mount would need mirrored material to read correctly through it.

• Wipers: set the lower edge above the wiper sweep, and above the parked blade if your wipers park high.
• Ice: clear the glass below the band and let the vinyl shed its own frost. A scraper finds the edge.
• Washing: fine once cured. Avoid pressure-washer jets aimed at an edge.

Removal is the gentlest in the vinyl world. Warm the strip with a hair dryer, peel from a corner, and clean residue with automotive adhesive remover.

Find the strip with the rest of the trim range in the exterior parts collection, alongside the 3M 10 ft door edge guard trim, which uses the same method on paint.
