Why would you use WD-40 as a lubricant. Technically it's a penetrant for freeing up stuck bolts and displacing water - Water Displacement-40. Many things have been ruined by people thinking that WD-40 is a long term lubricant and protectant. It ain't.

 

No problem at all. Many bikes get stored for winter after a full coating with WD-40. (except the tires).

 

WD-40's main ingredients, according to its U.S. Material Safety Data Sheet* information, are:

· 51% Stoddard solvent (i.e., mineral spirits: primarily hexane, somewhat similar to kerosene)
· 25% Liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
· 15+% Mineral oil (light lubricating oil)
· 10-% Inert ingredients

 

WD-40 is great for displacing moisture; we used to spray it inside of distributor caps that had condensation. For all other vehicle applications, there are better products.

 

WD-40 is the Duct Tape of lubes.
with a can of WD-40, a roll of duct tape, and a few zip ties, you can accomplish anything!

 

And when all that stuff dries and evaporates away it will have left an excellent surface for rust to work on.


You want to lube metal use a quality oil or grease. You want to protect a bare metal surface us GIBB Brand Penetrant.

The long-term active ingredient is a non-volatile viscous oil which remains on the surface to which it is applied, giving lubrication and protection from moisture
