Schaeffer's 163 RustStop Outdoor | 5-G

Schaeffer's 163 RustStop Outdoor (5-Gallons) is:

• solvent cutback,
• non-staining, 
• barium free,
• water-displacing.

This rust preventive is specially formulated to provide long term external protection. It is for ferrous, galvanized and non-ferrous metal parts and equipment stored outdoors. The heavy-duty protective residual soft rubbery film that is formed after evaporation of the solvent, is highly resistant to high humidity, acidic and salt containing atmospheres. This makes RustStop Outdoor particularly useful in long-term outdoor storage applications.

Schaeffer's RustStop Outdoor meets and exceeds the following specifications:

MIL-PRF-16173E Grade 4, and MIL-C-83933A.

Always consult the owner’s manual and the OEM’s recommendations for the correct fluid recommendations. More information available in technical data download.
