Applying Magnetic Signs
- Make sure the entire magnet is flat against the metal surface. Do not place over protrusions (molding, decals, pin striping, 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 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 resistance cause by the high magnetic strength.
- Do NOT use on horizontal metal surfaces to direct sunlight (such as automobile hoods), temperatures exceeding 160°F (71°C) or temperatures below -15°F (-26°C). Exposure to cold weather will make the magnet more brittle so use caution when handling.
- 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.
- Do NOT use magnetic signs on non-metallic body fillers, simulated wood grain siding and repainted surfaces.
- NOTE: Doors and panels on some vehicles are not made of steel. Magnetic signs will not work on aluminum and plastic surfaces.
- To guard against moisture and dirt buildup between the magnet and the metal surface (particularly on outdoor applications), remove the magnet at regular intervals. Clean both the magnet and metal surface with mild detergent; wipe with a soft cloth or allow to air-dry. (For vehicle-mounted signs, remove and clean weekly.)
- After waxing and polishing vehicle, allow 2 days for wax to cure before applying magnets.
- When not using signs, keep signs in a clean, dry place.
- Store flat to avoid curling.
