How Do You Fix a Rusted Truck Bed?

Rust on a truck bed can really take away from the vehicle’s look and value. It can also spread to other metal components on the truck, leading to more expensive repairs down the line. That’s why it’s important to address rust as soon as possible, and fortunately, there are a few easy steps you can take to fix a rusted truck bed.

Step 1: Cleaning

The first step in fixing a rusted truck bed is to give it a good cleaning. Use a hose and scrub brush, then rinse off with clean water. This will remove any debris or dirt that may be stuck in the rust and make it easier for you to assess the damage.

Step 2: Sanding

Once your truck bed is clean, use an electric sander equipped with 80-grit sandpaper to remove all of the rust. Make sure you sand thoroughly until all of the rust has been removed; if you don’t get all of it, then it could continue to spread.

Step 3: Priming

Once you’ve finished sanding, your next step is to apply a rust-inhibiting primer. This will help protect your truck bed from future rust damage. When applying primer, be sure to do so evenly and in thin coats.

Step 4: Painting

After your primer has had time to dry (check with manufacturer instructions for drying times), it’s time for painting. Make sure you use an automotive paint that is specifically designed for trucks; this will ensure that it holds up better against weather conditions like rain and snow. Again, apply thin coats until you achieve even coverage.


Fixing a rusted truck bed isn’t difficult or expensive if done correctly. By following these simple steps – cleaning, sanding, priming and painting – you’ll have your truck looking good as new in no time.
