Fair Advantage Automotive Services specializes in oil-based rustproofing and undercoating, protecting vehicles from corrosion caused by Midwest road salt and moisture. We focus on long-term rust prevention using proven products and professional application methods — no shortcuts, no rubberized coatings. 

We proudly serve customers throughout Anamosa, Jones County, and surrounding Eastern Iowa communities. Rustproofing is by appointment to ensure proper preparation, coverage, and cure time. 

Woolwax is a lanolin-based, oil undercoating and rustproofing product designed to protect vehicles from corrosion caused by road salt, moisture, and harsh Midwest weather. Unlike rubberized or asphalt-based coatings that can crack or trap moisture, Woolwax remains flexible and continues to creep into seams, welds, and hard-to-reach areas where rust typically starts.

One of Woolwax’s biggest advantages is that it does not dry out or harden over time. This allows it to self-heal, resist wash-off, and provide long-term protection without flaking or peeling. It is especially effective on frames, undercarriages, and internal cavities such as doors, rockers, and crossmembers

We chose Woolwax because it consistently performs in real-world Midwest conditions and aligns with our standards for long-term vehicle protection.
