Mine Spec 5 Rustproofing (Underground)

Beam Underground Mine Spec 5 Rustproofing Treatment is a comprehensive bituminous, wax and dry film rust treatment designed to combat corrosion in harsh conditions where the standard mining specification is inadequate. Spec 5 includes additional high risk areas such as the exhaust system and the electrical and hydraulic fittings / connections. This level of rust protection is suitable for vehicles engaged in underground mining and would be the minimum requirement for those used in salt and fertiliser works and coastal shipping facilities.
