For a truck owner, a bed liner is a necessary feature that will both protect cargo and prevent damage to the truck itself. In the past, the most common option was a drop-in liner but today there are many high-quality spray-on options that offer a more permanent solution. (We’ll share the best spray-on bed liners below.)
In general, drop-in liners are best if you plan to sell your truck in a few years or are looking for an easy install. If you want a protective liner that stands up to water and sand that doesn’t add unnecessary weight and noise to your vehicle, a spray-on liner is the better option.
As with most vehicle upgrades, you have two main routes when it comes to installing a spray-on liner: hire a professional or do it yourself. If you want to do it yourself, you’ve come to the right place. First, here’s where you can find instructions for both the brush-on and spray-on methods. (Note: For best results, follow the specific instructions that come with your kit.)

Now let’s talk supplies. If this is your first time applying a spray-on liner, you’ll need more than just the paint itself. The following kits will provide you with all the supplies you need for your project. Once you have a kit—and a free weekend—you’ll be ready to go!
