Magnets and applied vinyl solve different problems. Magnets are removable and depend heavily on the vehicle surface and maintenance. Applied lettering is usually cleaner and more consistent for a vehicle that represents the same business every day.
When magnets may fit
Magnets can make sense when the identification must be removed, the vehicle serves more than one purpose, and the body panel is flat, smooth, steel, and suitable for magnetic material.
When applied lettering may fit better
Applied vinyl is often a better fit for a dedicated work vehicle, permanent identification, complex door shapes, coordinated fleet graphics, and layouts that should stay in the same position.
Surface and care matter
Magnets must sit flat and stay clean on both sides. Dirt, moisture, curved panels, aluminum, body filler, and some repainted surfaces can create problems. Photos and vehicle details help confirm the practical option.
Materials and production decisions depend on the actual surface, environment, size, expected life, and installation conditions. Send photos when you can.
