Use the red scuff pad to scuff along the crack in the clear coat. Scuff along and near the crack, up to two or three inches on each side of the crack. Scuffing will make the clear coat appear dull. Scuff along the crack until it is no longer visible.
Wipe the scuffed areas with wax and grease remover and a towel. This removes any grease from fingerprints or wax from cleaners previously used on the hood. These contaminants will result in imperfections in the new clear coat.
Hold the can of clear coat paint six to eight inches from the surface. Spray along the scuffed area, covering all of the area that looks dull. Apply a total of three coats of clear coat paint. Let the paint dry for three hours before handling it. When dry, the area won't look dull and will blend with the entire hood.
