![]() Converting red oxide to black oxide wouldn't make much sense, because the red oxide is already ruined metal (truly 'rusted'), and wouldn't re-bond to the steel anyway it's lost metal, no matter what. In other words, forming the black oxide before the steel can truly rust in the first place (to red oxide: Fe2O3). ![]() The above quote would seem to make more sense, in that the conversion by boiling is directly from unoxidized clean steel ("metal that is capable of rusting") to black iron oxide. Magnetite (Fe3O4) is the black oxide of iron. I'd go nowhere near a toothpaste that's actually hard enough to abrade steel that'll wreck your teeth quick. It'll 'clean' it, if there's any lightly-stuck crud on a blade, but not much else (this is why it might remove some rust, because red iron oxide is very loosely-bound to the steel). The best one might expect in using toothpaste on a knife blade is that it'll do essentially the same for it, as for teeth. In other words, the abrasive is softer than the enamel, and the enamel is much softer than steel. Tooth enamel is softer than steel (much), and decent toothpastes will be abrasive enough to remove food stains/debris, but not abrasive enough to damage the enamel. ![]() It's just that the abrasive in toothpaste (it's called 'hydrated silica') generally isn't hard enough to abrade hardened steel, or the black iron oxide on it. This will provide a smooth and satiny finish.Toothpaste IS abrasive, correct. Further on finishing, you can also opt to gently buff with a fine buffing compound or use a spray wax that you like.This will provide a silky smooth surface and blend in the patina and non-patina areas. You can sand and put some patina on now and later some more! For an overall fine finish, you may consider wetsanding the whole surface quickly with 600-1500 grit wetsand paper.Be careful and go slow, if you see any white, STOP, this is the base vinyl. When you wetsand you slowly reveal the under color, which is typically a 'primer' like color. Film has a natural aged patina finish and you can augment it by wetsanding (600 grit wetsand kits available from us).Gentle heat from heat gun can be useful to relax wrinkles in vinyl or help conformity on curves, but heating and stretching is not necessary.Apply within 70-90 degrees to very clean and dry painted surface.Solid Drivability, weather resistant: drive in the rain, snow.Thicker and stronger than standard vinyl - provides valuable protection to original finish from rock chips & scratches. Fully conformable to body panels like any color change wrap.Many Colors: Rusted Wrap is available in colors on this page - and can be made to order in colors you specify (call to discuss your project - extra cost applies to metallic & custom colors).More still, it's sandable! In a few minutes create your own patina to reveal a 'primer' color layer where it would fall on natural body lines over years of weathering. Vinyl Wrap with an aged paint appearance and texture.Pricing on this page is based on two solid colors but custom options are also available for 3 colors and metallics if you want. RustedWrap is order made to the colors you want, so let us know in your order notes or by email.
