Lubricant - Spray Form and Waterproof
This spray lubricant for bikes was actually developed by Boeing (the airplane folks). It combines lubricants, solvents, and waxes and dries to a thin, waxy film that will stay on metal for months.
The spray also can be used to loosen rusty or corroded parts on your bike, and has been tested to be safe on paint, plastic, and vinyl.
Comes in a 4.0 oz spray can.
