Why Choose Car Magnets for Advertising?

Car magnets are the new game-changer in vehicle advertising, as it is both economical and easy to put on your car. Car advertising magnets provide a degree of convenience unmatched by permanent vinyl wraps and an impact that cannot be achieved without them. It takes only a few seconds to apply and remove them, and you can alternate the personal and professional use of your vehicle.

This flexibility is perfect for businesses that operate out of a single vehicle, such as a sole trader electrician or a real estate agent who uses their car for both client meetings and personal errands.

Car advertising magnets are not only the stickers on wheels, these are the portable advertising systems that can help your brand to get noticed.

  • Low Cost Marketing: Car magnets are cheap to advertise on compared to billboards or print advertisements, and are very noticeable.
  • Removable and Flexible: Customise and take them across a range of vehicles or take them off when not in use.
  • Professional Appearance: An effective magnet enhances credibility in an instant.
  • Local Exposure: This is ideal when it comes to businesses located in Brisbane that seek to capture the residents.

Small business owners, freelancers, or tradies will find that car magnets promote their brand 24/7 with every single trip to the shops, client visit, or delivery when wearing a car magnet.

Essential Maintenance Tips for Car Magnets

No matter how high-quality your car magnets may be, you have to treat them with care to ensure they deliver the best in a manner that is most effective. This can cause degradation of the magnet, the paintwork of the vehicle, and a not very professional finish.

To make the car advertising magnets long-lasting, maintenance is a vital activity. The following is what you must know:

1. Clean Magnet and Vehicle Regularly, The Golden Rule.

Dust, dirt and moisture can loosen the magnetic bond and discolour your paint. Clean the magnet and the area of the car at least once every week using a mild soap.

How to do it:

  • Carefully remove the magnet from your car
  • Wipe with a clean, soft cloth and a mild soap and water on the back of the magnet and the car seat.
  • Clean both surfaces well in clean water.
  • When both the magnet and the vehicle are dry, apply the magnet again.

2. Frequently Remove and Reapply

Permanently leaving car magnets behind can trap moisture and dirt that cause paint damage. Take them off now and then, clean both sides and put them on.

3. Avoid high temperatures

In the hot summers of Brisbane, car magnets may warp in response to high-intensity heat. When not in use, store magnets flat and in a place that is not under direct sunlight.
Tremendous heat may loosen the magnetic material and make it become non-adhesive.

Parking your car in the shade, particularly during the hottest times of the year, such as in Brisbane, is an easy yet efficient method of extending the shelf life of your automobile magnets. In case you want to place the vehicle under direct sunlight and in order to prevent magnets, it is better to take the magnets off.

4. Check for Air Bubbles

Apply by pushing outwards, in the centre. Bubbles will decrease adhesion, and magnets will fly off during driving.

5. Store Flat & Clean

Your magnets are never to be rolled or folded. Keep the magnetic sheet in a flat state on a smooth surface so that it can be stored to maintain perfect condition.

6. Storage is Essential

When not in use, it is important how you store car door advertising magnets. Do not keep them in a rolled or folded state. This can cause permanent folds that would make them impossible to lie flat on the vehicle and resulting in friction and poor connection, and could lead to them leaving the vehicle at high speed.

BEST PRACTICE: Place them on a non-magnetic surface (tables, a shelf) and ina flat position. To get optimal results, store in a cool, dry area without direct sunlight at room temperature.

Car Magnets in Brisbane – Why Quality Matters

When you are working in an area such as Brisbane, you are used to high temperatures and the heavy, unexpected rainstorms. These environments expose your car magnets to the toughest test. That is why it is impossible to invest in low quality.

Lower-grade magnets, especially cheaper ones, are more prone to UV damage, and it may cause a loss of colour, as well as making the material brittle. They are also less magnetic, and when moving at high speeds or during strong winds, they pick and remove much more easily. Our premium-grade magnets are created with a more powerful magnetic attraction and UV-resistant coating, so your logo will remain bright and safe, come rain or shine.

Brisbane businesses require magnets which are:

  • UV Resistant: to resist direct sunlight.
  • Waterproof and Weatherproof: They perform well in high winds.
  • Durable Vinyl Finish: long-lasting colour brilliance.
  • Safe on Car Paint: will not scratch paintwork.

When the businesses opt to use quality car advertising magnets in Brisbane, they are safeguarding their marketing spend as well as their car.
