How to Prepare a Vehicle for Graphics or a Wrap
Vinyl bonds to paint, not to wax or dirt. Paint condition, washing without wax, removing old decals, winter install constraints, and the aftercare that determines lifespan.
Start with the paint, honestly
Vinyl adheres to the surface it is applied to. If that surface is failing, the vinyl will fail with it — and worse, removing vinyl from compromised paint can take the paint with it.
Assess before you book: Is there rust, particularly bubbling under the paint? Is there clear coat peeling or flaking anywhere? Are there deep scratches or chips? Has any panel been repainted, and if so, when and by whom?
Rust and peeling clear coat must be repaired first. Applying vinyl over them hides the problem temporarily while it continues to spread underneath. When the graphics come off, you have a much bigger repair than you started with.
Original factory paint in good condition is ideal. It is what vinyl and its adhesives are formulated for.
Resprayed panels are the biggest risk. Fresh paint continues off-gassing solvents for weeks, and vinyl applied over it can bubble or fail to bond. A repaint typically needs several weeks to cure fully — confirm the timeline with whoever did the work and tell us, because this is not something we can assess by looking.
Washing it properly
“Clean” here means clean at a level normal car washing does not achieve. The enemy is anything that sits between adhesive and paint.
Wash a day or two before, not the same morning. Water trapped in panel gaps, door jambs, mirror housings and trim seeps out for hours and gets under vinyl edges at exactly the wrong moment. The vehicle needs to be genuinely dry throughout.
Use no wax, sealant, or protectant.This one is counter-intuitive: people wax the vehicle to present it nicely and actively sabotage the job. Wax exists to stop things bonding to your paint. Avoid any wash product that includes a wax or “shine” additive, and avoid automatic car washes that apply one by default.
Existing wax needs stripping if the vehicle has been waxed recently. Mention it — it changes the prep required.
Do not use tyre shine or trim dressing near the panels being wrapped. It migrates and it is greasy.
Old graphics, adhesive and fittings
Old decals must come off completely, including all adhesive residue. Vinyl applied over old adhesive telegraphs every edge and bump beneath it.
Be prepared for a possible surprise: if the previous graphics were on for years, the paint underneath may have faded at a different rate than the exposed paint around them. Removing old decals sometimes reveals a visible ghost outline. That is not damage caused by removal, but it can affect what your new layout should cover.
Some fittings may need removing for a clean install — badges, handles, mirrors, light housings and trim, depending on the coverage. Wrapping around a badge rather than removing it leaves a visible edge that catches at a car wash. Discuss what is coming off before install day.
Ladder racks, roof boxes and shelving on work vans should be considered too. If they obscure panels you are paying to have printed, either remove them for the install or design the layout around them.
The install itself
Vinyl needs warmth. Both the material and its adhesive behave poorly in cold, which is a genuine constraint through an Ottawa winter. Installation happens indoors in a heated space for this reason, and the vehicle itself needs to be up to temperature — a van driven in from −15°C needs time to warm through before work starts.
Plan for the vehicle to be off the road. How long depends on coverage: simple door lettering is quick, a full wrap is a multi-day job. Ask for a realistic window when you book and plan your work around it rather than hoping.
Empty the vehicle if panels are coming off or interior access is needed.
Leased vehicles: check your lease terms before committing. Most leases permit removable graphics but some restrict them, and end-of-lease inspection is not the moment to discover the rule. Magnetic signs sidestep the question entirely and are often the right answer for leased or personal vehicles.
Aftercare, which determines how long it lasts
Leave it alone for the first few days. Adhesive continues bonding after application. Avoid washing during that initial period, and avoid pressure washing entirely for longer — ask for the specific window when the job is handed over.
Hand wash is best. Automatic washes with brushes catch vinyl edges and lift them over time. Touchless washes are acceptable.
Keep pressure washers away from edges. If you must pressure wash, keep the nozzle well back and never aim directly at a seam or edge — that is exactly how water gets underneath and starts peeling.
Deal with fuel and chemical spills quickly. Petrol, diesel and solvents degrade vinyl. Wipe spills promptly rather than leaving them.
Parking matters more than people think. Constant direct sun accelerates fading, particularly on horizontal surfaces like the bonnet and roof. A vehicle garaged or parked in shade keeps its graphics looking sharp noticeably longer.
Deciding how much coverage you actually need
Preparation requirements scale with coverage, so this decision is worth making before you get too far.
Cut lettering and decals deliver most of the visibility for a fraction of a wrap’s cost. For most trades and delivery fleets, where the job is making a name and number legible, this is the sensible spend.
Partial wraps cover specific panels — typically the rear and lower sides — giving a full-colour presence without the cost of total coverage.
Full wraps make sense when the vehicle itself is a brand statement, or when the design needs to flow across the whole body.
Whatever the coverage, size the phone number for someone reading it from a car behind you at a light — see our comparison of wraps, decals and lettering.
Frequently asked questions
How should I prepare my vehicle for graphics?
Wash it thoroughly a day or two beforehand using no wax, sealant or protectant, and make sure it is fully dry including panel gaps and door jambs. Repair any rust or peeling clear coat first, remove old decals and adhesive completely, and confirm any repainted panel has fully cured.
Can I wax my car before getting a wrap?
No — this is the most common well-intentioned mistake. Wax exists specifically to stop things bonding to your paint, which is the opposite of what vinyl adhesive needs. Avoid wash products with wax or shine additives, and mention it if the vehicle has been waxed recently so the prep can account for it.
How long after a respray can I apply vehicle graphics?
Fresh paint off-gasses solvents for weeks and vinyl applied too early can bubble or fail to bond. A repaint typically needs several weeks to cure fully. Confirm the exact timeline with whoever did the paintwork and tell us — it is not something that can be assessed visually.
Will vehicle graphics damage my paint?
Quality vinyl applied to sound factory paint and removed properly is designed not to. The risks are with paint that is already failing — rust or peeling clear coat — and with vinyl left far beyond its intended life. On a leased vehicle, check the lease terms first; magnets avoid the question entirely.
Can vehicle graphics be installed in winter?
Yes, but installation happens indoors in a heated space because vinyl and its adhesive behave poorly in cold, and the vehicle itself needs time to warm through before work begins. Factor that into scheduling if you are booking during an Ottawa winter.
How do I wash a vehicle with graphics on it?
Hand wash where possible. Avoid automatic washes with brushes, which catch and lift vinyl edges over time — touchless is acceptable. Keep pressure washers well back and never aim directly at a seam or edge. Leave it unwashed entirely for the first few days while the adhesive finishes bonding.
