An old favorite is back... When Griot's Garage carried Mag Wheel & Aluminum Polish, it was considered the go-to polish for bringing back the brilliant shine to old, tarnished aluminum and magnesium finishes. Recently, Richard Griot tested it on non-clearcoated aluminum, steel, magnesium, stainless steel, Plexiglas®, plastic and acrylic surfaces only to discover that it's safe and effective on all of them! That's why Griot's Garage is re-introducing this amazing product as Griot's Garage Heavy-Duty Metal Polish! This polish is silicone free and water soluble making is easy to rinse off after use. Achieve amazing results when used by hand or with Griot's Garage Random Orbital. Conforms to commercial aviation requirements. Ever tried to polish a nine year old oxidized magnesium Indy Car wheel? That's exactly what Richard Griot did just to prove the effectiveness of this amazing polish... In fact, Griot's friends at J&L Fabricating tell me it's the best polish available for the aluminum tubs on the race cars they build.
