Solution

1. Preparation

Tools Required: Safety goggles, gloves, wire brush, sandpaper, rust inhibitor, primer, paint.
Clean the affected areas with soap and water, then dry thoroughly.
Remove any loose debris, dirt, and old paint from the rusted area.

2. Remove Rust

Tools Required: Angle grinder or rotary tool with a wire brush attachment, rust removal chemicals (if needed).
Use the wire brush or grinder to remove all visible rust until you reach bare metal.
If necessary, apply rust removal chemicals according to the manufacturer's instructions for stubborn rust.

3. Treat the Area

Tools Required: Rust converter or inhibitor.
Apply a rust converter to the bare metal areas to neutralize any remaining rust. Follow the product instructions for drying times.

4. Patch or Replace

If the rust has caused extensive damage, cut out the affected area with a metal cutting tool.
Tools Required: Sheet metal, welding equipment or bondo for patching.
Fit a new piece of sheet metal as a patch or apply bondo to fill in holes. Ensure it is shaped to fit snugly and securely.

5. Prime and Paint

Tools Required: Primer spray, automotive paint, clear coat.
Once the patch is secure and any body filler is sanded smooth, apply a coat of primer to the treated area.
After priming, apply the matching automotive paint, followed by a clear coat for protection.
