Park Tool's polyurea lubricant was developed specifically for bicycle maintenance and repair. PolyLube 1000 has an extremely high shear strength to protect vital parts under extreme conditions. PolyLube 1000 also repels moisture and is compatible with conventional greases. Caution: Some painted surfaces can be sensitive to oil and grease. Clean off any excess oil or grease immediately. Test first on an inconspicuous area to see if it causes a stain or discoloration.
