Brush on a light coating without allowing excess to spill over into the shielding barrel or on the electrodes. Mica-lube is
equally satisfactory for application on the shell threads only, in place of regular oxidation inhibitor. If mica-lube is used,
the spark plug needs no additional anti-seize application before installation.
Plugs that are stored after rust-proofing can be placed back in empty new plug cartons and properly identified. Rack
storage is also practical if the shell and electrode ends are covered with paper caps. In damp, humid and sea coast
areas, place the rust-proofed plugs in a closed cabinet, heated by a low wattage light bulb.
