Care and feeding of Door Magnets

Grab Bag - Misc.What to do with those door magnets.

If you follow these guidelines you will protect your paint and keep the magnet in good shape.

  1. When not using the door magnet, store it in a clean, dry place.
  2. If you can, stick the sign on a flat metal surface.
  3. Do not bend fold or mutilate
  4. Avoid placing objects on the top that could damage the face.
  5. Do not stack multiple magnets with magnetic sides facing each other.
  6. When placing the magnet on your car make sure the entire magnet is flat against the metal surface (.i.e., no air pockets)
  7. If you place the magnet in the wrong position, completely remove it from the surface and place it again.Do not pull the magnet across the surface or slide it. If there are any dirt particles (even fine dust) between the magnet and the metal surface, pulling the magnet across the surface could leave scratches. Remember that happens with those magnetic mount CB antennas?
  8. Avoid use on horizontal metal surfaces exposed to direct sunlight (such as automobile hoods) or temperatures exceeding 150° F (66° C).
  9. Avoid use on areas with non-metallic body fillers or simulated wood grain siding. Also avoid repainted surfaces with thick layers of paint. That can reduce optimal contact with metal surface, especially with the thinner magnetic stock.
  10. To protect fresh clear coat, base coat and/or vinyl surfaces on new vehicles, remove signs daily. Clean both surfaces before reapplying.

Door magnets may be made my gluing a waterproof vinyl decal onto a magnetic backing, by printing directly on to a white magnetic sheet, or, for those that I make, gluing a transparent sheet to white magnetic sheet stock.

The first two methods are generally waterproof, while my homemade magnets tend to suffer in the rain. That said, as long as you keep them off the car when it rains (What are you doing driving in the rain anyway?) you should be OK.
