Applying Magnetic Signs
- Make sure the entire magnet is flat against the metal surface. Do not place over protrusions (molding,decals, etc.) or concave areas. There must be NO air pockets.
- The magnet itself should be at a room temperature of 60°F (16°C) or above when installed to achieve best results.
- Do not apply magnet that has been curled with the magnet side out. The magnet may not attach properly to the metallic surface resulting in lifted corners or air gaps which will weaken its holding strength. Follow instructions for Storing Flexible Magnet.
- If you place the magnet in the wrong position, completely remove the magnet from the surface and reaffix. Lift at sides and not at corners to remove. Do not pull the magnet sign across the surface, or it may stretch due to the resistance caused by the high magnetic strength.
- Do NOT use on horizontal metal surfaces exposed to direct sunlight (such as automobile hoods), temperatures exceeding 160ºF (71ºC) or temperatures below -15ºF (-26ºC).
- Be aware that long-term use on surfaces frequently exposed to sunlight (such as vehicles) can result in uneven fading of the surface because the magnet-covered area is shielded from ultraviolet rays.
NOTE: Doors and panels on some vehicles are not made of steel. Magnetic signs will not work on aluminum and plastic surfaces.
