Yes! The Preval Sprayer is superior to a standard aerosol paint can for many reasons.
First, you can fill the Sprayer with the exact amount of paint you wish to use, minimizing waste. Second, you can add in hardeners, accelerators, catalysts to inexpensively create 2-component spray paints . Finally, standard aerosol cans allow paint to sit for long periods of time, becoming adulterated by mixing with the solvents and propellents. In the Preval Sprayer, paint and the propellant never mix in their liquid state.
The Sprayer holds less than 2oz. of propellant and sprays up to 16oz of paint or liquid OR 18 minutes continuously. For paint coverage see second page of Owners Manual –
