The product we use
FLUID FILM® protection.
Built for tough conditions.
We use FLUID FILM in natural/clear and black finishes. This lanolin-based corrosion preventive blends processed wool wax, refined oils, and corrosion-control ingredients. It stays soft and non-drying, forming a protective barrier on treated metal.
Reaches tight spaces
The coating creeps into seams and crevices to help protect areas where moisture can collect.
Helps resist winter exposure
Creates a barrier against corrosive road salts and brines on treated chassis surfaces.
Two finishes, the same purpose. Natural/clear has a light straw-colored appearance. Black adds pigment for a dark, uniform finish. Both remain soft rather than curing into a hard shell.
Preparation and upkeep matter. FLUID FILM does not remove rust or restore weakened metal. We assess preparation separately. Protection depends on exposure and use; ask us about inspections, refresh applications, and aftercare.
