🧲 Magnetic Signs for Vans & Cars: The Flexible Way to Advertise

When you pull up at a job, what do people see? A blank van — or your business name in bold, clear lettering?

Your van or car is one of the most valuable advertising tools you own. It goes everywhere you go: building sites, customer driveways, motorways, supermarket car parks. Every journey is a chance for potential customers to notice your brand.

But not everyone wants permanent vinyl graphics. If you lease your van, use your car for both work and personal life, or simply like the freedom to switch your branding on and off — magnetic signs for vans and cars are the perfect solution.

At Griffin Signs, we’ve helped thousands of UK trades and small businesses turn their vehicles into moving billboards with magnetic car door signs and custom panels. Let’s answer the most common questions people ask before buying.

What exactly are magnetic signs for vehicles?

Magnetic signs for vehicles are custom-printed panels made from flexible, high-strength magnetic sheeting. They’re designed to cling securely to flat metal panels on your van or car.

You’ll usually see them placed on:

• Van side doors

• Car doors (driver and passenger sides)

• Tailgates or rear panels

  
  

When you need them, they’re visible and professional. When you don’t, just peel them off and store them flat. That’s why magnetic advertising for cars and vans is so popular — flexible branding on your terms.

Are magnetic car door signs safe at speed?

This is one of the biggest questions people ask. The answer is yes — quality magnetic car door signs stay in place even at motorway speeds, provided they’re applied correctly.

Key tips for safety:

• Apply only to clean, flat, smooth surfaces

• Avoid fitting over curves, dents, or panel lines

• Press down firmly to ensure a strong bond

At Griffin Signs, we use vehicle-grade magnets engineered for outdoor use, so they won’t slide or lift when you’re driving at speed.

Will magnetic signs damage paintwork?

Done properly, magnetic signs for vans and cars won’t damage your paintwork. In fact, they can protect the paint beneath from UV fading.

⚠️ But there are a few golden rules:

• Don’t apply magnets to freshly sprayed paint – wait at least 90 days after respraying.

• Avoid fitting to freshly waxed panels – wait 3–5 days after waxing before applying.

• Always clean both the back of the magnet and the vehicle panel to avoid grit scratching the surface.

Follow those simple steps and your paintwork will stay safe.

Are magnetic signs weatherproof?

Yes. A good magnetic car sticker or panel is designed to handle the great British weather. Rain, frost, wind – no problem.

That said, regular care helps them last longer. Remove them now and again, give them a quick wipe, and reapply to keep the bond strong. In winter, it’s a good idea to remove them more often to prevent salt or grit build-up.

How long do magnetic signs last?

With proper care, magnetic advertising for cars and vans can last 3–5 years. That’s a solid return for a low-cost investment.

To get the most life out of your signs:

• Remove and clean weekly

• Store them flat in a dry place when not in use

• Never fold or roll them

• Wipe away dirt, dust, and moisture before reapplying

At Griffin Signs, we only use high-quality magnetic sheeting and fade-resistant inks, so your branding stays sharp for years.

Do I need to maintain magnetic signs regularly?

Yes — maintenance is key to keeping your signs looking professional and your paintwork protected.

Here’s a quick checklist:✔ Remove weekly and clean both sides✔ Dry fully before reapplying✔ Store flat, not rolled or bent✔ Check edges for trapped grit✔ In winter, clean more often to prevent road salt build-up

This simple routine takes just minutes but will extend the lifespan of your signs massively.

Magnetic signs vs vinyl graphics: which is better?

It depends on your needs.

• 🧲 Magnetic signs for vans:

  • Removable, reusable, flexible

  • Ideal for leased vans or cars used outside work

  • Perfect for trades who don’t always need constant branding

• 🎨 Vinyl graphics:

  • Permanent, long-lasting, always-on branding

  • Professional look that never comes off

  • Best for businesses wanting 24/7 visibility

At Griffin Signs, we supply both. Many customers actually start with magnetic car door signs to test their design, then move on to permanent vinyl once they’re ready.

Are magnetic signs cost-effective?

Yes. Compared to a full vinyl wrap (which can cost £1,500–£3,000), magnetic signs for vehicles are a fraction of the price. Yet they still give you professional visibility wherever you go.

For small businesses, self-employed trades, and start-ups, they’re a smart way to advertise without a huge upfront cost.
