After drying, use a nylon scrubbing pad to remove any spilled or excess repair liquid. The results are spectacular, where the sink resembles a new one. You can now use the sink.

Take the blue light and shine it on the tape covering the area covered with the repair liquid. Allow to light to shine for approximately 5 – 10 minutes.
Remove the tape after the time has expired and use sandpaper to smoothen the area. Ensure you use the finer grits of the sandpaper. Use a soft, damp cloth to wipe the dust away after sanding.
