Heavy-Duty Anti-Rust protects internal surfaces against rust Works with your undercoat spray gun to apply a black, waxy film that sticks to bare metal or painted surfaces, and won’t crack, flake or peel. Use inside frames, doors, rocker panels or on any exposed surface where painting will not be required.
Air-tight, watertight barrier prevents and slows rust
Ideal for rocker panels, frame, rails, tailgates
Self-heals if scratched
1-qt. can covers 20 sq. ft.
Heavy-Duty Anti-Rust produces a satin black, waxy, oily finish that flows into crevices, then sets as a flexible, watertight coating. Use it to protect freshly machined surfaces and bare metal parts in storage, and also to seal inaccessible body seams.
