Rust happens—but it doesn’t have to stick around. Whether it’s a few bubbling spots on your wheel well or surface corrosion along your rocker panels, removing rust is a manageable DIY project with the right tools, techniques, and a little patience. Here’s how to tackle it.
What You’ll Need:
- Safety gear (gloves, mask, safety glasses)
- Sandpaper (various grits: 80, 120, 220)
- Wire brush or drill-mounted wire wheel
- Rust converter or primer
- Body filler (if needed)
- Clean rags and degreaser
- Touch-up or spray paint
- Clearcoat (optional)
Step 1:
Assess the Rust
Not all rust is equal. If it’s surface rust (cosmetic), you’re in good shape for a DIY fix. If the rust has created holes or is spreading under panels, you may need professional body work. For anything in between, a careful repair job can still save the panel.
Step 2:
Clean the Surface
Wash the vehicle with soap and water to remove any water-soluable contaminants. While still wet, dry with another rag. Then use a grease and wax remover and a lint-free rag to wipe down the area, removing any oil-based contaminants. Any leftover dust, oils, or debris can interfere with primers and paints, so take a moment to make sure it’s completely clean.
Step 3:
Sand It Down
Start with coarse sandpaper or a wire brush to remove loose rust and paint. You want to get down to clean, bare metal—no flaky bits or orange dust. Feather out the edges of the surrounding paint so your repair blends more naturally.
Step 4:
Apply Rust Converter or Primer
If there’s still some embedded rust you can’t remove completely, apply a rust converter—it chemically neutralizes rust and prevents it from spreading. Follow the product instructions for drying times before applying a primer to prepare the surface for painting.
Step 5:
Fill (If Needed)
If rust has eaten into the metal, fill the area with an automotive body filler. Once it’s cured, sand it smooth, tapering into the surrounding panel. Finish with multiple coats of primer before paint.
Step 6:
Paint and Protect
Apply several medium coats of automotive paint that matches your vehicle. Follow with a clearcoat if your vehicle was painted with Basecoat /Clearcoat from the factory. Always check the label for recommended drying time between coats.
Step 7:
Buff and Blend (Optional)
Once everything is fully dry and cured (usually 30 days), you can lightly polish the area with a mild polish to blend the new paint into the old. This step is optional but helps make the repair less noticeable.
Final Tip
Keep an eye on previous rust spots over time. Even with a good repair, moisture and salt can sneak back in—especially in northern climates—so checking and touching up as needed will keep your vehicle in great shape.
