Aerosol cans are available in Black, Gray, Brown, Hilite (white), Gold, and Silver. Since a portion of the aerosol can must be used for the propellant gas, no aerosol can compare with the Airmite for spraying economy. Aerosols are not recommended for production but are handy for cemetery use or when shop air is abnormally wet. No aerosol will spray well when cold. Hold can about ten inches from stone. Too far will result in a "dry" spray.
