Directions for use 1. Clean oil from the target surface with a cleaner. 2. Apply directly from the bottle and allow to dry completely. 3. Cut out the area to be painted and remove any other unnecessary sections, then paint. 4. Remove the masking fluid after the top coat has dried completely. ★Apply the masking fluid after the base coat has dried completely. ★Apply a thin coat. (It takes about 30 minutes to dry.) Thicker coats will take time to dry. ★Use a new model knife blade when cutting dried masking fluid. Press and hold the edges of the dried fluid that have space underneath. ★This fluid is water-based.
