FAQ
Do magnetic signs damage car paint?
Not on clean, sound paint. Damage only comes from grit or moisture trapped underneath and left for weeks in the sun. Remove and clean the magnet regularly and your paint stays perfect.
Are there magnets that won't damage car paint?
Any quality laminated magnet is safe on clean, undamaged paint, so the magnet is never really the problem. What protects paint is the routine, not a special magnet: keep the panel clean and dry, and lift the sign off often.
How often should I take a car magnet off in summer?
In an Adelaide summer, every few days if the car sits outside, and at least weekly otherwise. Heat plus time is what lets trapped grit or moisture mark the paint, so more sun means more frequent lifting.
Can I put a magnet on a freshly painted panel?
Not straight away. New paint or a respray needs to cure, usually around 30 days, before a magnet goes on. Check with your painter first.
