Does Corrosion FREE apply a black undercoating to the bottom of the vehicle?
No, that’s very bad for today’s newer vehicles! Black tar like or waxy coatings are just a ‘cover up’. They seal moisture against the metal and in most cases when they flake or peel off, rusty holes appear on the previously coated surface. Because Corrosion FREE product is clear and you can see through it, you know it really works. It makes the underbody look great too.
