This is an oil based product for the treatment of chrome and other metals (see below). It leaves a protective film with a low surface tension that disperses moisture from pores within the metal's surface. This eliminates further rusting and corrosion salts from appearing, even when stored in a damp garage over winter. Winter Chrome Protector leaves a dry-to-the touch film with a higher build than penetrating oils, offering extra protection. Simply apply with a cloth, leave for 10-15 minutes and wipe off excess with a clean cloth. It is easily removed with white spirit followed by car shampoo.
