A custom magnetic sign is the perfect way to get your business or personal message seen by thousands. A magnetic sign on your vehicle enables you to advertise wherever you drive and gives you the flexibility to easily remove it when you want. Magnetic sheeting (0.030 in. thick) is used for signs that can be temporarily affixed to any vehicle or steel surface without being permanent. If you want to advertise your business by day and remove the signs after hours, magnetic signs are the ideal application. Your magnetic signs will arrive with rounded corners to add more quality by preserving the signs in high wind conditions. Most applications require purchasing two or more magnetic signs for both sides of the vehicle and on the back panel of trucks. Get more mileage from your marketing with magnetic signs.
