Cavity Protection

Protect hidden cavities in vehicle bodywork—door interiors, side panels, boot lids and sills—using cavity wax and rust-protection sprays. These penetrating formulations flow into seams and blind spots to displace moisture and form a durable corrosion-inhibiting film. Applied with an injector tube, spray lance or UBC/body gun, cavity protection prevents rust, paint chipping and internal abrasion, extending structural life. LAKGRUPPEN supplies a range of cavity waxes, rust-protection sprays and applicators for professional and DIY use.
