This works...but you need practice on using it. Best if you have scraps of glass to practice on. Spray will drip and goof up everything from time to time. Wipe the nozzle and purge by turning upside down and pressing the spray. Allow to dry for 24 hours before you pick it up. Best if not exposed directly to light when dry. Then the irregularities are not too noticeable. The problem comes from uneven application when spraying....just like spray paint. But it is better than using a brush for larger areas.
