The feature of magnetic signs, which is touted in advertisements, sounds tempting: the advertising can be removed from the car as often as you like and remounted in a matter of seconds.

This is made possible by a magnetic coating behind the digital print on a robust PVC coating, which is optimally laminated and protected against wind and weather.

What sounds so simple has its pitfalls.

What you should definitely consider when buying magnetic signs

A magnet is not a permanent attachment. Magnetic adhesion is the only thing that allows the magnetic foil to "stick" firmly to the car body.

1. Modern cars are no longer made entirely of metal.
Before you decide on a magnetic sign, use a small kitchen magnet to check whether your car doors or the place where you want to attach the magnetic sign is actually magnetic, because modern cars are often made of plastic or light metal (aluminum alloys), which are not necessarily magnetic.

2. Magnetic signs are NOT suitable for long-term use.
Many proud magnetic sign owners have had a rude awakening when they had to remove a magnetic sign that had been left hanging for a long time.
This resulted in permanent and unsightly bonds between the magnetic material and the car body or unsightly abrasion damage to the paintwork.


Why is explained in detail here:

+ Unwanted, permanent connection
The magnetic side of the shield is enclosed in a soft plastic
to reduce friction between the metal part of the shield and the
To minimize car paint and thus prevent damage.

Especially in the warm season (summer) this soft plastic is
heated to such an extent that melting phenomena may occur.
These components can stick and permanently bond to the paint
or the body.

Especially if this happens repeatedly over a longer period of time, damage such as
in the picture below.

+ Abrasion damage and sanding

Another very common phenomenon is scratches and sanding marks
on the paint underneath.

This is explained as follows:
The magnetic connection is not an adhesive bond, as is the case with a glued
foil, but a magnetic attraction. Especially liquid and
Fine dust particles easily get between the magnetic shield and the
varnish and remain there.
Due to wind and expansion and contraction of the material during
Temperature differences create a continuous sequence of mini-
movements, so that the magnetic shield constantly moves like sandpaper
on the paint. Even without particles in between, this results in
abrasive effect over a longer period of time. Long-term remaining dirt
between the shield and the car paint, this effect is further increased.

We consistently recommend only placing a magnetic sign on the bodywork on a daily basis
and when removing the surface underneath with a
Microfiber cloth to rub dry and clean.

+ Discoloration of the paint

If the drug is not removed for a longer period of time, an effect occurs which we also see in
long-term observation of cars with foil labels. With a
However, magnetic signage can counteract this.

Long-term exposure to sunlight changes car paint. Wind and weather control
The paint "shoots off" as the saying goes. It loses
in brilliance and shine - becomes slightly matt.
This can be counteracted with regular paint care and polishing, but
cannot be completely prevented.

However, if a magnetic shield is permanently attached, this protects
Magnetic shield, the underlying paint to a certain extent
the influence of the weather and thus the contours of the sign are later on
visible on the paint.

We therefore strongly recommend not to use magnetic signs for long periods of time on
the car and regularly clean the area underneath
to be professionally maintained with cleaning utensils and polish.

Your car paint will thank you.
