Di itrol ML4 is a Swedish >yst m employing a petroleum ,vax product with a high :api lary action able to penet-ate and protect narrow crevices often left unprotected against corrosion in manufacture.
Ford and Renault are among the companies who now automatically provide rustproofing for the light end of their commercial vehicle ranges.
Ford uses the Crodametal oil-based system on Escort and Fiesta vans, applied on the production line. No extra guarantee is given over normal one-year period. Renault uses APC5, a resinbased product manufactured by the Valvoline Oil Co and applied as an additiona item after the vehicle has left the production line.
The Renault 4 van is the company's only commercial model protected by the system and is given a five-year guarantee against corrosion, providing the vehicle is resubmitted for inspection after 18 months and again after 42 months.
