Is the gallon jug worth it over spray cans?

Yes if you use WD-40 often. The gallon costs far less per ounce, but you need a spray bottle or trigger to apply it.

Can I use WD-40 as a long-term lubricant?

Only for light duty. It is a thin, solvent-based lubricant that evaporates; use grease or a dedicated oil for bearings and high-load parts.

Is it safe on plastic and rubber?

WD-40 says it has none to negligible effect on common plastics and rubbers such as HDPE, Teflon, neoprene and hard rubber, plus most metals.

It penetrates and frees rusted parts and loosens corrosion, but it does not dissolve heavy rust. Mechanical work may still be needed.

How should I store and apply it?

Keep the jug sealed away from heat and flames. Pour into a labeled spray bottle or trigger for precise use.
