Car Magnet Signs, Magnetic Car Signs & Custom Truck Magnets for Business & Personal Vehicles

Most popular

Contractors & trades car magnets

Car magnet signs for contractors, plumbers, electricians, and HVAC technicians who drive personal vehicles to job sites — company name, license number, and phone number on the door in the format that says "professional" when you pull up to a client's driveway. Peel off before school pickup.

Truck magnets & magnetic signs for trucks

Truck magnets for business fleets, work trucks, and personal pickups used for contracting — magnetic door signs sized for full-size truck doors (12" × 24" or 18" × 24"), magnetic signs for trucks in large format to maximize text legibility at distance. Truck magnets for business that swap between multiple drivers or vehicles without re-ordering.

Real estate agent car magnets

Magnetic car signs for real estate agents driving to showings, open houses, and client appointments — headshot, name, brokerage, and phone number on a format that turns the car door into a business card. The vehicle magnet that drives inbound calls from neighbors at every showing without a permanent wrap commitment.

Van magnets & magnetic van signs

Magnetic van signs for catering vans, cleaning service vehicles, delivery vans, and cargo vehicles — the long flat door panels of a van provide the maximum visible canvas for magnetic car signs. Van magnets in full-size panels that cover the entire cargo door and read from across a parking lot.

Gig workers & delivery drivers

Magnetic door signs for delivery drivers, florists, caterers, and mobile service businesses identifying their vehicle for curbside drop-offs — "Flowers," "Catering," or a company name on a format that applies and removes in one motion. The alternative to putting a permanent sticker on a leased vehicle.

Events, parades & magnetic bumper stickers

Magnetic bumper stickers and parade car signs for temporary vehicle branding at festivals, political campaigns, and community events — the format that applies for the event and removes without residue. Custom magnetic bumper stickers that make no long-term commitment to any cause or candidate.

Are car magnets safe for paint?

Yes — when applied and maintained correctly. The risk to paint comes from trapped dirt between the magnet and the door surface, not from the magnet itself. A small amount of grit acts as sandpaper when the car flexes at highway speed. The fix is simple: remove the magnet weekly, wipe the back surface of the magnet and the car door with a damp cloth, and reapply. This ensures a vacuum-tight seal that eliminates micro-movement and keeps the paint beneath the magnet in the same condition as when you applied it. Never apply a car magnet sign over a pre-existing scratch or chip — moisture can collect there.

Will car magnets stick to my vehicle?

Magnetic car signs require a steel body panel to adhere — and most vehicles have steel doors and quarter panels. The common exceptions are aluminum body trucks (newer Ford F-150, some RAM variants), fiberglass panels (hoods and some bumper areas), and carbon fiber or plastic body trim. The easiest test: hold a standard fridge magnet against the panel you want to use. If it sticks firmly, our 30 mil magnetic signs will hold at highway speed. If it barely clings, our heavy-duty magnets may still work but with reduced security. If it falls off immediately, that panel is non-magnetic and won't support any magnetic sign.

How fast can I drive with car magnet signs?

Our 30 mil magnetic car signs are rated for highway speeds when applied to a clean, flat, steel surface. The factors that cause magnets to detach at speed are: dirt buildup reducing adhesion (solved by weekly wiping), curved surfaces where the magnet can't achieve full contact (place magnets only on flat door panels, not over body lines or curves), and magnet placement in high-turbulence zones (avoid the leading edge of front doors and the area directly behind wheel wells). If your magnet has ever shifted or nearly detached at speed, remove it, clean both surfaces thoroughly, and reapply from the center outward to eliminate air pockets.

What should I put on a car magnet sign for business?

The most effective car magnets for business include: company name in the largest legible font the sign area allows, a single phone number (not website and phone — choose one for mobile readability), and the service category if the company name doesn't make it obvious ("Smith & Sons — Plumbing & HVAC"). A logo is useful if it's simple and reads at distance; a complex multi-color logo often reads as noise at 35 mph. License or certification numbers add credibility for contractors and trades. For real estate agents, a headshot occupying the left third of the sign with contact information on the right is the most proven format — face recognition is the differentiator at a glance.

Can I use the same magnets on multiple vehicles?

Yes — this is one of the primary advantages of magnetic car signs over vinyl wraps or permanent door lettering. A set of magnets can move between a personal vehicle, a company truck, and a rental van as needed. Store them flat (not rolled, which weakens the magnetic material over time) between uses. For fleet applications where the same design needs to appear on multiple vehicles of different sizes, order the sizes appropriate to each vehicle type and label each set. The 30 mil magnetic material retains its adhesion through hundreds of application-and-removal cycles when stored correctly.
