How to Fix Rust on a Car Roof
Fixing a rusty car roof involves several steps, depending on the severity of the damage.
Assessing the Damage
The first step is to determine how extensive the rust is. Surface rust can often be treated with rust converter and primer. However, if the rust has penetrated the metal, you might need to patch or replace the affected area.

- Wire brush or sandpaper
- Rust converter
- Primer
- Automotive paint
- Clear coat sealant
- Body filler (if needed)
- Sanding block

Removing the Rust
Use a wire brush or sandpaper to remove all loose rust and paint. This will create a clean surface for the rust converter to adhere to. Be sure to wear safety glasses and gloves during this process.
Applying Rust Converter
Apply rust converter to the affected area following the manufacturer’s instructions. This will chemically convert the rust into a more stable compound and prevent further rusting.
Priming and Painting
Once the rust converter has dried, apply primer to the area. This will provide a good base for the paint. After the primer dries, apply several thin coats of automotive paint, allowing each coat to dry before applying the next. Finally, apply a clear coat sealant to protect the paint and prevent further rust.
Repairing Holes
