Rust Protection and Prevention


Despite recent advances in the materials and manufacture of vehicles, corrosion is still with us. You can hardly miss the effects of rust as you commute to and from work. The sight of cars and trucks with rusty fenders, doors and frames is as common now as it was decades ago. In fact, the need for corrosion protection has become more urgent that ever.

Why is this? Many transportation experts blame the new generation of road de-icing chemicals, particularly magnesium chloride. This compound forms a crystalline film on the body and the windows of vehicles that is difficult to wash off. Magnesium Chloride draws moisture from the air and the residue on the vehicle becomes actively corrosive at humidity rates below 25 percent. Adding to the threat is the fact that many government entities use magnesium chloride for dust control on dirt and gravel roads. For many vehicles exposed to a range of driving conditions, magnesium chloride can be a year-round problem, not just a seasonal one.

Fortunately, rust/corrosion prevention is still possible. By following a regular program of corrosion prevention coating, anti-corrosion spray, and other maintenance, you can keep your car in excellent condition.

Step 3:
Floor mats and seat covers
Technicians are careful to ensure each vehicle has a floor mat cover and plastic seat cover to ensure your vehicle leaves exactly as it was brought in.

Step 4:
Light housing removed
On certain vehicles, tail lights are removed to allow easier access to the rear sections of the vehicle. This helps to ensure a thorough application.

Step 5:
Holes are drilled
Before each vehicle is treated, technicians review the service bulletins for detailed access areas for each specific vehicle before drilling access holes

Step 6:
Vehicle is treated
Technicians access all corrosion-prone areas of your vehicle with specialized tools to ensure complete protection.

Step 7:
Holes are greased and plugged
After all the areas of your vehicle have been treated, each area is inspected, greased and all drilled holes are plugged with a specialized grommet.

Step 8:
Vehicle is washed
Your vehicle is then washed with Krown's specialty soap which removes any excess Krown product from the painted surfaces

Step 9:
Treatment completed, keys delivered
Your vehicle is returned to you clean and protected from rust!

The best warranty in the business
Krown has protected vehicles from rust since 1986 and we work hard to create the best customer experience we can. That means standing behind the best warranty in the business. Whether you have just purchased a new vehicle and want the best rust protection possible, or have been a Krown customer for years, Krown has got you covered with both our new and used vehicle warranty program.

Research and Development.
Through years of experience, and a devoted research and development team, Krown has been able to combine break-through innovation with gradual improvement to deliver the #1 rust protection in Canada. Krown's rust protection product is a leap forward in innovation. Through testing and research in some of the harshest climates in Canada and the eastern United States, Krown has developed a superior product to withstand high humidity, constant exposure to corrosive road salt, and abrasion from road dirt and debris. We work hard to look at corrosion, salt and cleaning needs from all angles, developing products such as our new Salt Eliminator and others that quickly deliver results.

Environmental Responsibility
Krown contains no solvents, no VOC’s (volatile organic compounds) and no toxins. Krown could use more harmful yet cheaper ingredients in their product but they have chosen not to do so. In the manufacturing process, environmentally-friendly ingredients almost always cost more than other more harmful alternatives. Yet Krown feels that the lessened impact to our planet makes the additional expenses they incur more than worthwhile. On top of that, what if Krown could use a recycled, refined and re-cleaned product as one of their ingredients as well? That’s exactly what they do. In fact over 80% of the ingredients in the Krown product are made up of re-refined materials and additives.

Bullet Liner is a product invented and produced by Claudio Burtin. He is the principal founder of Line-X. After he sold LineX corporation, and properly waited out a non-compete clause, he was then able to develop and launch Bullet Liner. There are some major differences between the two, mostly being the UV stability and gloss retention properties of Bullet Liner over LineX. Think of it this way. He made LineX over 2 decades ago, and now Bullet is a newer, more advanced product. Think how much technology has changed in the past 20 years! Bullet Liner is an all around better product for the applicator and the customer.

Chevrolet Forum

From recent inquiries it appears as though many installers of Line-X bed liners have abandoned their franchises and switched over to Bullet bed liners. It seems the same engineering genius (chemical engineer), who invented the used in Line-X, sold the company, and started up a new company using, "new an improved" products. Apparently there are a few improvements in the application and also the Line-X was prone to some sun fading and supposedly the Bullet process is more fade resistant.

F150 Forum

That is true that the designer of linex started Bullet and from what I am told he is in Georgia. My 4Wheel Parts store knows him personally and from what they told me, he has taken Linex's flaws and improved upon them. One of the problems I have had with Linex on two different trucks is that after awhile it blackwashes. You can wipe the chalky residue off with your hand. My buddy got the Bullet and it is a much better product. It stays shiny (I think it has UV protectors in it) and it doesn't chalk up. With Bullet, you don't need those revitalizing sprays they sell for Linex and Rhino to keep them new looking.

Oceanside did the LineX on my previous truck and they do awesome work. The shop has been around for a long time and the owner says they will stand by the product. He explained to me why they switched. Without bashing LineX he told me that Bullet is a superior product. The guy who invented LineX sold the company and name about five years ago. His chemical company developed a new coating and he decided to start a new venture instead of selling the compound. So far, the dealers that have signed on with Bullet Liner are former LineX dealers who have jumped ship, like Oceaside. I went to the shop and spoke with them in person and they showed me some examples. I was impressed, especially with the much lower price over LineX Premium. I will be getting Bullet Liner sprayed on my truck next week!

I got it done with the Bullet Liner product. I did research and found that the guy who started Line-X sold it and he started Bullet Liner. Also, I got high recommendations by my friend who run an Auto shop next door to the Bullet Liner guys.
