The magnet must adhere very firmly to the vehicle. If it seems to you that a child might be able to pull it off, then it is definitely mounted too loosely.
Magnetic bases only adhere to steel sheet metal. Never use a magnetic base on vehicles made of aluminium, such as some vehicles offered by Audi or Mercedes. Never use a magnetic base on vehicle parts made of aluminium, stainless steel, plastic or other non-magnetic materials of a car body.
The magnets can only adhere firmly if they are in full contact with the surface. Never use a magnetic base on curved vehicle sheet metal. Air might flow under the magnet and loosen it. Therefore look all around the base under the magnet to verify that it is lying flat and cleanly. If not, please look for another, more even mounting location on your vehicle.
Never place a magnetic base over edges.
Never use a magnetic base on repainted surfaces.
Each additional paint increases the gap between the vehicle sheet metal and the magnetic base, thereby reducing the magnetic effect.
Magnetism only acts between the vehicle sheet metal and the magnets themselves.
For the same reason, areas that have been repaired with tin or bonding compound,
etc. are also unsuitable as mounting locations for the car flag.
Never use a dirty magnetic base.
Never use a magnetic base on a dirty vehicle surface.
Here too, the dirt increases the gap between the vehicle sheet metal and the magnet itself, thereby reducing the magnetic effect.
By the way, dirt can also lead to paint damage. The magnetic base and the mounting surface on the vehicle must be clean, dust-free and dry.
Never use a magnetic base at temperatures near or below the freezing point. Ice or snow build-up between the magnetic base and the vehicle sheet metal would increase the distance between them and thereby reduce the magnetic effect. |
