Decals are used to add visual graphics to vehicles for various purposes such as branding, decoration, safety, and promotional messaging.

Magnets are typically used to display temporary messages or items, while emblems are permanent fixtures that often represent a brand, group, or organization.

To apply a decal to a curved surface, use a heat gun or hairdryer to gently warm the decal and make it pliable, then carefully apply it to the surface and press down firmly.

Emblems can be made from a variety of materials such as metal, plastic, and rubber. The choice of material depends on factors like durability, weight, and ease of installation.
