The magnetic sheet and metal surface MUST be clean and dry. In any outdoor application, such as car signs, the metal surface should be waxed.
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 the resistance caused by the high magnetic strength. Make sure the entire magnet is against the metal surface (no air pockets).
Some moisture and dirt will collect between the magnet and metal surface, particularly in outside applications (car signs).
REMOVE WEEKLY AND CLEAN BOTH THE SURFACE AND THE MAGNETIC SIGN
The magnet is more pliable and easier to work with when it is near room temperature when applied. When storing in rolls, wrap the coated surface on the outside to avoid the possibility of wrinkles.
