Prep The Working Area

Repairing the rust in truck bed begins with cleaning and scraping all the rust.

To commence, cover up the space that the rust has not harmed, employing several layers of masking tape or paper for maximum defense.

To remove the truck bed rust, use a wire brush and some sandpaper, but always be cautious not to scratch the adjacent surfaces.

Eliminate All The Rust Using A Drill Or Wire Brush Wheel

Regarding how to fix a rusted truck bed, after you’ve entirely wrapped the truck bed parts, which are still intact, start erasing rust by using a wire brush wheel and drill.

The objective is to let off the rust as rapidly as possible using a harsh technique involving a lot of manual labor.

Don’t fret if you pierce the bed or slightly expand a hole during the session. Keep going until you run out of rust to remove.

Sand Down All Residual Rust

After discarding whatever, you can go over any places with 80-grit sandpaper to remove any residual rust on truck bed.

Remember that painted surfaces can also be affected by rust, which can seep beneath the surface. Scrape some paint from the sanded area’s margins for rusted truck bed repair.

Next, sand that area using 150-grit paper to smooth it. This will strengthen the adhesion of paint and patching materials.

Wash Off The Sediment & Dust

Remove Dust & The Sediment

After you’ve finished sanding, cleanse your truck bed to get rid of all the silt, road debris, road salts, and dirt that have gathered. Check it carefully to make sure there is no corrosion left.

Take Advantage Of A Rust Restorer Or Chemical Rust Remover

Be sure to employ a rust restorer or a chemical rust remover as an extra layer of assurance to treat all the rust and finish the task.

Adhere to all label instructions, particularly those that necessitate proper protective gear.

Weld The Problematic Patches & Paint Your Truck Bed

Once the truck bed is free of dirt and moisture, cover the exposed metal with rust-inhibiting paint.

Ensure to apply a thin, even coat, paying close attention to the margins of any cracks or areas where the paint has chipped off, such as the bed’s underside.

Use Body Filler

When corrosion and rust cause holes, body filler is appropriate for tackling the issue.

Yet just before you begin mixing your filler, you must apply the patching mesh and other elements included with the patching kit.

After that, apply your patching mesh, following the manufacturer’s guidelines. If the ratios are off, the filler can solidify too rapidly or even not at all. Thus, you must adhere to the directions strictly.

You should also know that all fillers will harden after mixing. You’ll need to move swiftly until you fill all holes. Do not care about how aesthetically nice it is.

Sand Your Patch Down Smooth

The filler usually hardens in about 2 hours, though this time frame might range from product to product.

The filler must dry before sanding it nicely with 150-grit paper. It’s best to start at the top and proceed downward the body using an increasingly finer grit.

Apply Primer Properly

Once you are satisfied with the patch’s smoothness, prime the patch and any exposed metal with an auto primer.

After waiting an hour for the primer to finish, sand the place down to 400 grit. Apply another coat of primer, wait until it’s dry, and then sand it down again using the identical paper.

Restore Your Finish

The next day, after the primer dries after applying a second layer and smoothes the surface, wash and dry your truck bed again. You must have the truck primed before repainting it.

Paint should be applied in three separate coats for the most significant effects, with each coat being sanded in between with 400-grit sandpaper, much like the primer.

Once you’re done with the third layer, sand that area down to a clean finish once more, but now, wet the paper to leave a smoother, more refined look.

Add a clear coat after the last layer gets dried to protect the paint job. This coating is significantly more robust than the paint layer and safeguards the underlying layers.

It also makes the truck’s bed look sleek and polished.

After the clear coat dries, peel off the masking tape and wipe the area sparingly. Although not required, wax the space for extra defense and aesthetics.

These fixes typically persist for 5 years or more before they need to be retouched.

Still, especially during the initial year, it’s a good idea to examine the repaired area regularly to ensure no additional rust accumulates.
