Apply and cure bonding agent (Bio Bond, Bonder Intense or Base Bond). Now wipe the dispersion film off of the nail with a clean, dry lint-free cotton swab. This will provide a better surface to apply the French application, as it will not run into the dispersion film. *Be sure that there are no lint particles on the nail from the cotton swab. Using the application brush, swipe it across the nail plate to form the nice crisp smile line, cure.
