Once a small family-owned company in Santa Ana, California, Line-X now has over 500 locations in 46 countries and is the recognized industry leader in spray-on protective coatings. In fact, Line-X was the inventor of the industry’s first high-tech spray-on elastomer polyurea. Today, we continue to innovate and produce the highest quality materials to meet the needs of consumers in commercial, industrial, agricultural, and military settings.

Line-X systems utilize a two-component, environmentally friendly, spray-in-place,100% solids thermoplastic polyurethane and polyurea. Our products are fast-cure and designed for a wide range of uses. They exhibit excellent adhesion to most properly prepared surfaces, and there are no solvents which means there are no air pollutants or harmful environmental contaminates.

From truck protection to Jeep customizations or commercial applications, Line-X of Knoxville does it all. We provide unmatched protection, nearly indestructible spray-on bedliners, and a huge selection of truck and Jeep accessories for all lifestyles and needs.

Lifetime Warranty

At LINE-X of Knoxville, we are so confident in the quality of our bedliners that we were the first in the industry to offer a nationwide limited lifetime warranty.

No Lost Cargo Space

Your vehicle accessories will fit perfectly due to the way LINE-X contours to your truckbed. Since LINE-X is sprayed directly on the surface of your truck, it ensures a permanent bond and a watertight seal that leaves plenty of room for your bed lid, 5th wheel hitch, camper shell, and whatever else you need to customize your vehicle.

LIN E-X has a higher tensile strength than any of the competition, and independent tests show it is resistant to most chemicals including chlorine, gasoline, diesel fuel, bleach, and most household solvents.

Value Added

Every professionally applied LINE-X bedliner adds life to your vehicle with tough polymers engineered to create a weather and watertight seal able to withstand years of heavy-duty use in most weather conditions.

What Our Customers are Saying

I would like to thank you and your crew at Line-X of Knoxville for the outstanding job you all did on my brand spankin new Dodge Ram 3500 MegaCab. The job that your crew did exceeded my expectations. The bed liner and the Westin step rails have made my Ram one awesome truck. Thank you again,

Thomas Fortsch, Jr.

When I drive around town I see a lot of the Line X stickers in the back windows of trucks and I can see why. Line X of Knoxville is the best place to go for a bedliner for my F150 truck. They were able to match the bedliner to the factory color of the truck. The staff was very knowledgeable and worked very hard to make sure I was taking care of. If you are thinking about having a spray on bed liner for your truck or vehicle I recommend Line X of Knoxville. You will not be disappointed.

I had a LINE-X sprayed on yesterday. When I got home and had an opportunity to look at it, I was extremely impressed! You did a fantastic job! I was especially pleased with the fact that you even cover the area down between the bed and tailgate, where rust can very easily develop. It looked even better than I had imagined! Thanks!

Thank you for your help coating the decorations for our children’s sanctuary. I recognize that the giving of your time and those who helped you was no small sacrifice. The project was huge.  As I write, the pieces are being painted. Soon they will go up along with the other appointments that we have planned to create a unique and exciting atmosphere that will go beyond inviting kids. They will be drawn. From there we will develop a spititual environment that is just right for introducing kids to Jesus and teaching them His ways.

So many roles to be played- I thank God for yours.

God bless you all,

Doug Swilley, Children’s Pastor Redemption Chuch
