What is Krown?

Krown is designed to slow down or inhibit corrosion on vehicles. It is a petroleum based product with rust inhibitors containing no solvents. Krown products are environmentally safe, contains no toxins or solvents, is non-flammable, is non-reactive, is non-corrosive, can be sprayed in any weather, and remains active.

Does it drip? Why and for how long?Ohio Car Rust Proofing and Prevention

The product must get into the seams and around spot welds to work effectively. It is moisture that causes corrosion, so an effective rust inhibitor needs to be thin enough to penetrate anywhere that water can. After the product has penetrated these areas, the excess product drips off. The majority of the dripping occurs within 24-48 hours with very little, if any, dripping after that point. Don’t worry Krown is environmentally-friendly.

What if it drips on my driveway?

If your driveway is asphalt the marks on your driveway will go away on their own usually after a week or two. If your driveway is concrete or interlocking brick your local Krown location can provide you with a special cleaning product that will remove the stains with very little effort.

How does it work?

Krown is sprayed in every corner of the vehicle and as it contacts metal, it lifts the moisture off and out of seams. It then continues to repel moisture by setting up a moisture resistant bond on the surface of the metal.

Can you apply Krown to rusty cars?

Both new and used vehicles are susceptible to rust and our product works on both. Krown is absorbed into existing corrosion and pushes out any moisture, thus slowing any further corrosion down significantly.

What locations do you service with Krown rust protection?

Gus’s Garage applies Krown rust protection to vehicles in the Dayton Ohio area including Piqua Ohio, Troy Ohio, Sidney Ohio, Greenville Ohio, Celina Ohio, St. Mary’s Ohio, Richmond Indiana, Muncie Indiana, and the surrounding area. If you are from the Columbus Ohio area, Cincinnati Ohio area, Indianapolis Indiana area, or Lima Ohio area give us a call as well! We can apply this terrific rust preventative treatment to your car or truck at our location in Versailles Ohio.

What is the best time of year to have my car sprayed?

If your vehicle has never been protected, then the best time to spray it is right now. From a corrosion point of view, the corrosion process is most active in the spring and summer months due to the increase in temperature. However, an annual application of Krown, regardless of the time of year of year it is applied in, will provide 12 months protection against corrosion.

How do you know where to spray?

Krown technicians go to training seminars every year to learn how to spray as well as to receive updates on the new techniques for current vehicles. Training videos demonstrating the proper application process are also used to ensure that the correct procedure for application is performed on all vehicles. We are the only company in the industry with this comprehensive training program.

Doesn’t washing the vehicle defeat the purpose of treating it? Won’t the product wash off?

After your vehicle is sprayed with Krown at one of our locations, your vehicle receives a wash. We are cleaning the excess product off of the windows and painted surfaces where the product is not active. The rust inhibitor itself cannot be removed from the metal with soap and water.

Why do you have to drill holes and will these holes rust?Removes salt from vehicle before rust protection

Certain areas of a vehicle can only be accessed by drilling or cutting small holes in key spots. These holes are treated with a special compound so even if the vehicle is never sprayed again these areas will not rust. Each hole is then plugged with a special plastic cap that leaves a clean, neat finish.

Will Krown void my manufacturers warranty?

Krown will NOT void any manufacturer’s warranty. However, many car salesmen do tell people this untruth. If someone makes this claim, ask them to put it in writing and then contact the manufacturer directly.

How does Krown compare to competitive products?

In laboratory tests, Krown has outperformed all of our competitors. Copies of test results are available at any of our Krown locations.

What makes Krown different from other rust proofing products?

Many companies use “coating” products that are designed to cover over areas that are susceptible to rust. These products may look nice but they do not provide adequate protection against corrosion. For example, these types of coatings can be breached by abrasion or chipping. When this happens, moisture can enter in under the coating and become trapped against the vehicle surface. In this situation the coating will actually accelerate corrosion rather than prevent it. Krown by comparison is self-healing and is constantly “creeping”, remaining active to continuously repel moisture and keep it away from the metal surface.

In addition, unlike “coating-type” products, Krown penetrates into even the tightest seams and spot welds delivering a much more effective and comprehensive protection. One final difference is the added benefit that Krown offers of lubricating many moving parts on a vehicle such as door locks, brake cables, power antennas, etc. Coating products cannot do this.

Can Krown be sprayed even if it’s raining or snowing?

Absolutely, Krown can be effectively applied in any type of weather.

Is Krown environmentally friendly?

Yes, The Krown rust proofing product is also an environmentally friendly product containing no VOC’s, Solvents, Phosphates, or APE/NPE’s.

Do I have to do it every year?

To ensure that your vehicle is adequately protected, it is essential to have it treated every year. Especially these days when extremely aggressive road chemicals are in use for de-icing our roads, make sure you come in for a treatment every year.

How much does a Krown application cost?

The annual cost to spray a vehicle differs depending on the vehicle type. However, regardless of what you drive, the cost of an annual Krown application is far outweighed by the thousands of dollars you will save over the life cycle of your vehicle. An annual application also maintains your Krown warranty and “locked-in” price.

Does Krown offer a warranty against corrosion?

Yes.  Krown offers both new and used warranties on vehicles that qualify. You can get more information on the warranty available here.
