How to install
From Cars Wrap Supplies — follow this guide for clean results and fewer headaches. If you’re new, start with easier, flat panels (bonnet, roof, doors) before tackling bumpers and mirrors.

Before You Start
Ideal conditions
- Indoors, dust-free, 18–24 °C ambient temp
- Panels cool to the touch
- Good lighting (overhead + portable)
Tools you’ll need
- Microfibre cloths, lint-free towels
- pH-neutral wash, clay bar + lubricant (optional but helpful)
- Isopropyl alcohol (IPA 70%) in a spray bottle
- Masking tape, magnets
- Knifeless tape (Finish Line & Design Line)
- Felt-edged squeegees (soft & firm), hard card for edges
- Heat gun with temp readout (or IR thermometer)
- Wrap gloves, cutting tape, spare blades
- Tape measure, soft seam roller
- Cotton swabs, small detail brushes
Safety
- Wear gloves and eye protection.
- Disconnect battery if you’ll remove exterior trims with airbags/sensors nearby.
- Never heat near fuel fillers or on flammable residues.
Step 1 — Prep the Vehicle (Most Important)
1. Wash with pH-neutral shampoo. Rinse thoroughly.
2. Decontaminate: Clay the paint with plenty of lube to remove bonded grime.
3. Dry completely (air blow seams, mirrors, badges).
4. Degrease: Wipe panels, edges and recesses with 70% IPA. Use cotton swabs in panel gaps.
5. Remove or loosen obstacles where practical: badges, aerials, mirrors, plates, trims, wipers. Bag screws/clips.
Pro tip: Any wax, silicone or polishing oils left behind will cause lifting. Spend 70% of your time on prep — it pays off.
Step 2 — Plan the Job
- Panel order: Roof → Bonnet → Boot → Doors → Guards → Bumpers → Mirrors/handles.
- Measure & cut sheets with 5–10 cm extra all around. Keep pieces labelled.
- Mark centre lines with masking tape on both car and film backing.
- Decide seam strategy: Use knifeless tape for colour-change wraps around difficult joins; aim for 10–15 mm overlaps hidden on body lines.
- Recess depth check: Deep channels (>10 mm) may need inlays rather than stretching one piece.
Step 3 — Position & Tack
1. Float the film: Two people hold the sheet by the edges, adhesive facing down but not touching.
2. Anchor a small centre area (5–10 cm) with light squeegee pressure.
3. Set tension, not stretch: Gently pre-tension the sheet to remove big wrinkles without pulling hard.
Step 4 — Lay & Squeegee
- Work from centre → out in smooth, overlapping strokes (5–7 cm).
- Keep the squeegee angle ~45°. Use felt-edge for faces, hard card for edges.
- If you see a crease forming, lift back past the flaw, add a puff of heat, and lay again. Don’t chase it with the squeegee.
Curves & Recesses
- Warm the film to 40–50 °C to make it pliable (not hot).
- Bridge the recess, then push film into the valley with short strokes; avoid dragging stretch across sharp corners.
- For deep channels, use the triangle technique (create small relief triangles in excess film at the perimeter, not in sight lines).
Step 5 — Edges, Seams & Inlays
- Wrap around edges by 10–15 mm where possible.
- Use knifeless tape along body lines for invisible cuts. Pull the filament back on itself slowly.
- Where one-piece coverage would over-stretch, use an inlay (a separate piece laid first in the recess), then cover with the main panel.
- Aim for seams on natural panel breaks; when unavoidable, place overlaps away from direct sight and with the airflow.
Step 6 — Trim Cleanly (No Cut on Paint)
- Use knifeless tape wherever you can.
- If you must knife cut, use minimal pressure, new blade, and a tape buffer beneath the cut line.
- After trimming, be with firm squeegee/roller pressure.
Step 7 — Post-Heat (Critical for Durability)
- All edges, corners, stretched areas and recesses must be post-heated to the film maker’s spec: Typical target: 90–100 °C for moderate stretches; 100–110 °C for deep stretches.
- Use an IR thermometer. Heat evenly and hold pressure on edges as they cool to set memory.
Step 8 — Final Check & Cure
- Inspect under different lighting. Address bubbles (see below).
- Keep car indoors and dry for 24 hours; avoid washing for 48–72 hours.
Troubleshooting
Trapped air/bubbles:
- Tiny: leave; they often dissipate.
-
Larger: warm slightly, prick with a pin at the edge, squeegee air to hole.
- Edge lifting: Clean area with IPA, warm to 60–70 °C, press and hold. If contaminated, remove section and replace.
- Silvering (micro air): Lift, add gentle heat, re-squeegee with shorter strokes.
- Wrinkles that won’t lay: Stop, lift well past the wrinkle, add heat, re-tension and lay. Don’t force it flat.
Special Panels
- Bumpers: Complex curves; plan multiple pieces with inlays. Hide seams under grille lines or on lower lips.
- Mirrors/handles: Usually two pieces per mirror (face + inner), or one if film/shape allows and you can post-heat correctly.
- Roof/bonnet: Use magnets and a centre hinge. Watch for antenna holes; remove aerial and finish with a neat gasket or inlay.
Aftercare (Short Version)
- Do not wash car for 5 - 7 days after installation to allow vinyl to lock into place.
- Weekly washes with pH-neutral shampoo; avoid brush washes.
- See our full Care Guide for Aussie conditions.
Common Mistakes to Avoid
- Over-stretching beyond ~10–15% — colour/lightness changes and memory failure later.
- Skipping post-heat on edges and recesses.
- Cutting on paint without protection.
- Wrapping over wax, silicone or polish residues.
- Installing in cold (<15 °C) or hot (>30 °C) conditions.
