Magnetics on your vehicle allow "promotion with portability". Small businesses use magnetics to convert private vehicles into delivery cars without putting graphics directly on the vehicle. Magnetics allow large companies to employ leased vehicles as corporate cars and trucks, again without putting graphics on the vehicle. Magnetic signs are usually purchased either 2 or 3 per vehicle, with the third magnetic commonly being put on the rear for maximum exposure. Your company name, logo, phone number and a short description of the services/products you provide are the right ingredients for your magnetic signs.
