●  Peel the release paper back from one end and press the tape firmly onto the surface.

●  Removing the backing tape as you proceed.

●  On angles and grooves press firmly into the angle or groove first.

●  For a smooth finish, press tape with a rubber hand roller, working from the center ●  outwards, remove any air bubbles and creases ensuring firm contact is made with the surface.
