Materials

Aerosol paints are an extremely versatile type of paint that leaves a smooth, evenly covered surface. Ideally suited for touch-ups, structured steel, handrails, piping, equipment, machinery, doors, bolts, seams, vehicle refinishing, playgrounds, utility locating, stenciling, golf course and athletic field marking, signage, lockers, conduit and many more.

Application Tips: Shake the aerosol can well before using to minimize the
chance of the tip clogging. Be sure to shake the can for at least one minute once
the marble is heard.

Limitations

Mostly available in alkyds - (not suitable for severe
environments due to fair outdoor gloss retention)
Small package size
Potential for overspray
