Modified Harbor Freight pressurized paint sprayer. It no longer will spray paint, but hook up your compressor, put your silicone molds filled with two-part urethane inside, batten down the hatches and start the air. Run it to about 60 psi and it should hold it for a few hours so your castings will come out bubble-free.
