Salt is not the primary cause of corrosion but in the presence of moisture on metal it does greatly accelerate corrosion. If you have a small fire burning and add gasoline the gasoline greatly accelerates the fire. Salt is an accelerant much like gasoline. Moisture on metal - not salt - is the Number 1 cause of corrosion. If a product is thick and heavy, it tends to ‘coat’ the existing corrosion, trap condensation and moisture underneath and in many cases actually accelerates corrosion. Krown is absorbed into existing corrosion and pushes out any moisture present, thus significantly slowing the corrosion process. + Is Krown effective in treating vehicles with existing rust?īoth new and used vehicles have rust on them and the Krown Rust Control product works on either. However, with interlocking brick, it is recommended not to park on it for a couple of days due to the fact that the brick is very porous and tends to absorb the stain and the spots will stay much longer than on asphalt or concrete before eventually disappearing. Any spotting that shows on a paved or concrete driveway will eventually disappear by itself. There is nothing in the product to harm asphalt or concrete and it will not eat into pavement like oil does. Generally speaking, within about 6 – 8 hours most of the dripping is done. The majority of the dripping occurs within 24 hours with very little, if any, dripping after that point. With Krown, beyond the ‘film’ that bonds to the metal, a small amount of excess product will weep gradually from drain ports at the bottom of the doors and from some of the seams. Unfortunately, most corrosion gets started in areas not visible to the eye. Thicker, heavier products may give the consumer some ease of mind that a lot of something has been sprayed in open spaces where it can be seen. Products that contain thixotropic agents such as paraffin or wax are too thick, too heavy to get where most corrosion begins, that is inside tight seams and crevices where condensation and moisture can collect. Thickness has nothing to do with proper corrosion protection. Once the ‘oily’ film bonds to the metal, more product will not bond on top of the film. Therefore, it has to be fluid enough to penetrate. The product must get into the seams and around spot welds to work effectively. If a product will not displace and repel moisture, it cannot do an effective job in controlling corrosion. It would take fairly aggressive chemicals to take the product off bare metal. Krown is not water soluble and will not wash off bare metal with water or soaps. It then continues to repel moisture by setting up a moisture resistant bond on the surface of the metal. It ‘creeps’ into tight seams and crevices and will physically lift moisture off the metal and expel it. Krown is sprayed in every corner of the vehicle and as it contacts metal it bonds an ‘oily’ type film tenaciously to the metal. Krown is as safe a product as can be found in the marketplace for inhibiting corrosion on motor vehicles. The testing involved is fairly aggressive. The Federal Government (Canadian Food Inspection Agency) has done testing and has approved Krown for use in food plans where there might be some 'incidental' food contact. Krown contains no solvents, kerosene, gasoline, no paraffin or wax, no lanolin, no toxic chemicals, nothing of a cancer causing nature, no aggressive chemicals of any kind - making Krown absolutely environmentally friendly. It is a petroleum-based product, heavily fortified with rust inhibitors. It is a complex mixture of chemicals designed to slow down or inhibit corrosion on vehicles.
