For most Nashville drivers, every two to three years. Lanolin resists washout and self-heals, so it lasts longer than oil-based products. Heavy mileage, frequent off-pavement driving, or aggressive winter exposure shortens that interval.

The product can drip slightly during the first 48 hours, especially in warm weather. Tarps stay down during the service. After the initial setting period, residue is minimal. We recommend parking on cardboard or in a garage for the first day.

Yes. Lanolin penetrates existing rust and blocks the moisture and oxygen the chemical reaction needs to continue. It does not reverse rust that is already there, but it stops further progression. For vehicles with significant existing corrosion, this is the most cost-effective way to extend their useful life.

Lanolin is inert. It does not damage rubber bushings, plastic components, electrical connections, or paint. It does not interfere with sensors, brakes, or exhaust function.

A clean undercarriage helps. If you have time, a quick rinse with a hose under the vehicle removes loose debris. If not, our techs will scrape what needs scraping when we arrive.

If you plan to keep the vehicle for more than five years, yes. Surface rust starts forming on new vehicles during transport from factory to dealer. Catching it early extends the protection significantly. The cumulative effect of repeat coatings is real.

Permanent coatings cost three to six times more and create a hard shell that eventually cracks. When that happens, moisture gets trapped underneath the coating, which is worse than no coating at all. Lanolin remains flexible. It can be inspected and touched up in specific areas. We believe the long-term performance is better, especially in a humid climate like Tennessee.
