Surface Preparation
The magnetic sheet and metal surface should be clean and dry. In any outdoor application, such as car signs, the metal surface should be waxed.
Application
Magnetic sheet holds best to flat surfaces and surfaces reasonably curved in one direction.
When the magnet is placed in the wrong position, remove the magnet and realign. Do not pull the magnet to realign when it is against the surface, as the magnet may stretch due to resistance caused by the high magnetic strength.
Make sure the entire magnet is against the metal surface (no air pockets).
Cleaning
Some moisture and dirt will collect between the magnet and metal surface, particularly in outside applications (car signs).
Remove and clean both the magnet and surface with mild detergent and allow both to dry. For car signs, repeat the cleaning process weekly.
To protect the new clear coat/base coat and vinyl surfaces present on new cars and trucks, we recommend daily removal of magnetic signs. We do not recommend applying magnetic material to repainted surfaces.
Storage
The magnet is more pliable and easier to work with when it is near room temperature when applied. It is OK if the vehicle is very cold.
The best way to store the magnetic signs is either flat (a refrigerator, filing cabinet or clothes washer work great) or in rolls. Never magnet to magnet.
When storing in rolls, roll the coated surface to the outside to avoid the possibility of wrinkles.
