That is not what we like to hear! Our Rust-Oleum Imagine Glitter Spray Paints contain larger glitter pigments, and shaking is especially important prior to pressing the spray nozzle for the first time. If a clog has occurred, you can try spraying the can upside down to clear the nozzle, however, if the can has clogged inside, there is unfortunately no way to clear the clog. Please give us a call at 800-481-4785, we want to try to make things right! - Rust-Oleum Product Support 2
