Can You Use Custom Magnets for Outdoor Applications?

It depends on the magnet. Car magnets are made for the outdoors. Business card and lenticular magnets are indoor products that will not survive weather.

• Car Magnets: weather-resistant backing and a UV- and moisture-protected face make them outdoor-ready.
• Before applying: clean both the magnet and the vehicle surface so trapped dirt does not scratch the paint.
• Business Card and 3D Lenticular Magnets: fine on a fridge or office whiteboard, but not for mailboxes or exterior use.
• Bigger outdoor signage: yard signs or banners are the better tool when a magnet is not enough.
