Peel off one corner of the backing and cut off with scissors. Arrange sticker on model and when satisfied adhere the corner without
backing.
Carefully peel back the rest of the backing while at the same time adhering the rest of the sticker.
Try not to make air bubbles, if there are some, carefully puncture sticker (center of bubble) but not model surface with the tip of the knife
or sharp pin and
squeeze out the air. At curves stretch sticker and apply a little heat so that no ceases occur. Cut off the excess that is produced.
