The Berkebile Oil Company Protection First Class is designed to combat rust and corrosion and provide long-term lubrication. Protection First Class uses a non-toxic and solvent-free wool-wax formula that is clear and self-healing. It can be sprayed on almost all hard surfaces and will not impair a technician's ability to visually inspect the undercarriage of a vehicle. No respirators or protective suits are required, and overspray can be wiped away with a clean cloth.
