Berkebile Undercoating

Berkebile Undercoating: Decades of Proven Rust Protection

Berkebile Oil Company has been a trusted name in automotive chemical protection since 1954. Where the brand truly stands apart is in the undercoating category, where it has developed two distinctly different — yet equally effective — approaches to shielding vehicle underbodies from the relentless threat of rust and corrosion.

Protection First Class (PFC): A Lanolin-Based Innovation

Berkebile's flagship undercoating product line is Protection First Class (PFC), which takes a fundamentally different approach from conventional rubberized coatings. The lanolin-based formula of Protection First Class gives long-lasting protection from rust and corrosion by covering the metal with an amber film that will not wash off, collect dust, or dry out like oil, silicone, and solvent-based products. This is not just a surface barrier — the unique formula penetrates the pores of the metal, protecting it from moisture, salt, and corrosion.

One of the most compelling features of PFC is its self-healing barrier technology. PFC creates a self-healing barrier that continues to coat long after water-soluble or solvent-based products have evaporated or worn off. What's more, PFC's translucent film is easy to see through and diagnose problems before they happen — unlike rubberized undercoating, which can mask problems and allow rust to grow and spread under its surface. It lasts for up to a year, is easy to remove, is inexpensive, and is easy to reapply.

PFC is available in both a classic amber (clear) finish and a PFC Black formulation for those who prefer a more traditional, finished appearance under their vehicle. Undercoating solutions are tailored for various applications such as trucking, agriculture, and industrial use — making PFC just as relevant on a farm truck or heavy equipment as it is on a daily driver.

2+2 Rubberized Undercoat: Traditional Protection Refined

For drivers who prefer a classic rubberized approach, Berkebile also offers its 2+2 Rubberized Undercoat. Berkebile 2+2 Rubberized Undercoat is specially formulated to protect automotive underbodies from corrosion. It cures to a tack-free film that is paintable and has good abrasion resistance and effective sound-deadening properties, and can be applied to create a thick coating that stretches without cracking. This makes it a solid choice for restorers and daily-driver owners alike who want a hard, durable shell on vulnerable underbody panels.

Virgin Chemicals and American Manufacturing

What underpins both product lines is Berkebile's commitment to quality at the formulation level. Instead of recycled chemicals or factory seconds, Berkebile uses all virgin chemicals. Berkebile Oil has been known throughout the automotive industry for their high quality and great customer service and delivery since 1954. That consistency in sourcing translates directly into more reliable, longer-lasting protection on the road — or the farm, the job site, or the water.

Which Berkebile Undercoating Is Right for You?

• PFC (Protection First Class): Best for drivers who want a flexible, self-healing, translucent coating that allows inspection of the metal underneath — ideal for longer-term corrosion management.
• PFC Black: Same lanolin-based formula as PFC but with a dark finish for a cleaner undercarriage appearance.
• 2+2 Rubberized Undercoat: Best for those seeking a hard, paintable, sound-deadening traditional undercoat on panels and underbody surfaces.
