Hey, It’s Waylon “Joe” Kite here. I am a West Virginia native and a die-hard pickup truck fan. My story with trucks started with my dad’s 1989 Ford F-150, and it's still going on. I'll share all my trucking experiences (both great and gross ones) with you. I have a garage full of tools to fix and renovate trucks and a freezer full of ales. Do you want to join me?

Can you picture a car being left in your yard? It would be rather lunatic to visualize the vehicle getting scratched and spreading.

No, you won’t allow that!

But you’ll still receive complaints because the rock chips will never stop hitting your truck’s body. You can accept that but don’t like to have scars that destroy the beauty of your car’s lower portion? No doubt, the rocker panels are the main victims.

There’s always a solution. A bedliner guard is a convenient one. And you can do that alone in less time and with less money.

But how much bedliner does it take to do rocker panels? Keep reading to learn.

How Much Bedliner Does It Take to Do Rocker Panels?

Ever thought of the role rocker panels play in your vehicles? Maybe just because you’ve seen it in every car and never bothered. Or, you were never aware of it before the moment of a big problem that requires a permanent solution.

Well, to give you a clear idea about rocker panels, you can’t drive a car like a car without them. These two vital parts exist to connect the vehicle’s front and backside.

Therefore, if you have any idea about painting or spraying a coating on something, the calculation may match your guess.

You’ll find different types of liquid bedliner in the market. The amount of the element to apply on the same area shouldn’t be different. But how much to buy depends on the size of the cans in which the product comes.

For easy understanding, let’s assume the bottles of the U-Pol Raptor Black Urethane Spray-On Truck Bed Liner Kit w/Free Spray Gun, 4 Liters, carries the standard amount. The package includes four 750ml raptor bottles and 1L hardener tin.

Therefore, two bottles of raptor will be enough for two rocker panels.

Applying Bedliner on Rocker Panels

At this stage, we’ll discuss applying a bedliner on rocker panels. We’ll use the raptor liner in this process.

Essential Materials

  • Plastic bag covers
  • Yello tapes
  • U-Pol Raptor Black Urethane Spray-On Truck Bed Liner Kit w/Free Spray Gun, 4 Liters
  • Spray machine
  • Air compressor paint sprayer
  • Sandpaper and rubbing alcohol (if needed).

Now, let’s get started if you are all set with the necessary materials.

Step 1: Do the Wrapping

Cover the whole truck, especially the windows, with plastic bags, and don’t forget the wheels. It will keep the sections unaffected and safe from spilled chemicals.

Select the area where you’ll apply the bedliner. It’s a straight line from the front to the back wheel end with a range of 8 to 10 inches in width from the lowest point of the car.

Do it according to the car and your preference. Stick the yellow tape on both sides. It’ll keep the level straight.

Consider sticking another tape line over the edge of the tape line to reduce the chance of uneven spreading.

Step 2: Prepare the Liner

It’s time to work with the raptor liner.

Take one of the raptor liner bottles. You can feel a line on its upper level with your hand. Rather, it’s very visible.

Pour some raptor hardener up to that line. Seal the cap and shake it to make a good mixture. It’s ready.

Step 3: Spray Bedliner

Connect the bottle’s mouth with the spray machine and air compressor. You can select the rate of the spray by setting the meter on the system.

If it’s manual, be careful with your gut about the amount of spraying.

After the setup is done, point the spray’s mouth on the surface. Spray and move it left and right, so the surface gets the coating properly. Make sure you haven’t missed any part.

As you’re done with spraying, give it 30 minutes to set on the surface. Finally, take off the plastic bag cover. Your truck is ready to be on the road, and its rocker panel is safe from scratches.

Cautions and Suggestions

  • Be careful when you stick the tapes on the rocker. The lines on the two sides should be parallel, or it will trouble you.
  • Consider applying the bedliner on the fenders if you have some extra raptor left. Also, that can be applicable for some rear and backside of the vehicle. Those two areas are always prone to rust. Don’t forget to stick tapes at the outer part to specify the area. That’ll also keep the fender and other areas safe from the rock chips.
  • Take care of the rust first, if there’s any. Use sandpaper to make the surface prepared for the guard. Wiping the surface with a little rubbing alcohol will also be good.
