How to Fix Rust Around Windshield

Tiny rocks constantly bombard windshields, and other debris kicked up from the road, which can cause small chips and cracks in the glass. Over time, these chips can turn into bigger cracks and, if left untreated, can eventually lead to the need for a new windshield. In addition to being unsightly, rust around your windshield can also weaken the structure of your car and make it more susceptible to damage in an accident.

Summary: If you’re experiencing rust around your windshield, there are a few things you can do to fix the problem. First, try using a rust preventative spray or paste. Second, if the rust is severe, you may need to replace the windshield.

Why Does Rust Form Around Windshields Specifically

There are a few key reasons why rust tends to form around windshields. For one thing, the metal frame that holds the windshield in place is often made of steel. As a result, steel is susceptible to rust, especially when exposed to moisture and oxygen.

One other reason is that windshields are at the very front of the car. They are constantly hit by road debris, salt, and other corrosive materials. All of this can damage the metal frame and cause it to rust over time.

If you live in an area with a lot of snow and salt on the roads, you’re particularly at risk of developing rust around your windshield.

How Can Rust Affect the Structural Integrity of Your Car

If you take a close look at your car, you’ll notice that the main body is made of metal – usually steel or aluminum. Over time, these metals can develop rust, which can weaken and eventually break the metal if it’s severe enough.

Rust can also affect the paint job on your car. Paint can chip and flake off, exposing the bare metal beneath. This leaves your vehicle vulnerable to further rusting and damage.

If rusting is severe, it can cause electrical problems by causing wires to short circuit or break. This can be dangerous and should be fixed as soon as possible.

If your car has rust on it, you should take care of it right away. The longer you wait, the worse the problem can get. There are a few different ways to remove rust from your car.

A Detailed Guide on How to Fix Rust Around Windshield

Step 1: Gather Necessary Tools and Materials

Before beginning the rust repair process, gather all the necessary tools and materials, including:

  • Safety goggles and gloves
  • Painter’s tape
  • Plastic sheeting
  • Automotive paint and primer
  • Rust converter
  • Body filler
  • Sandpaper (80-grit, 180-grit, and 400-grit)
  • Wire brush
  • Paint thinner
  • Paintbrush or paint sprayer
  • Clear coat
  • Microfiber cloth
  • Masking tape
  • Utility knife
  • Auto glass sealant

Step 2: Protect the Windshield and Surrounding Areas

Before starting the rust removal process, use painter’s tape and plastic sheeting to protect the windshield and surrounding areas of your vehicle. This will help prevent any damage or contamination from the rust repair process.

Step 3: Assess the Severity of the Rust

Inspect the rusted area around the windshield to determine the severity of the rust. If the rust is only surface-level, it can likely be treated without removing the windshield. However, if the rust is more extensive and has eaten through the metal, the windshield may need to be removed to complete the repair properly.

Step 4: Remove Loose Rust and Debris

Using a wire brush, remove any loose rust and debris from the affected area. Be sure to wear safety goggles and gloves during this process to protect yourself from rust particles.

Step 5: Apply Rust Converter

Apply a rust converter to the rusted area according to the manufacturer’s instructions. This product will chemically convert the rust into a more stable, paintable surface, preventing further rust development.

Step 6: Sand the Area

Once the rust converter has dried, use 80-grit sandpaper to sand the area until it is smooth and even with the surrounding metal. Be sure to remove any remaining rust and debris during this process.

Step 7: Apply Body Filler

Mix and apply the body filler according to the manufacturer’s instructions. Use a putty knife to spread the filler evenly over the treated area, ensuring that it is level with the surrounding metal. Allow the filler to dry and harden as per the manufacturer’s recommendations.

Step 8: Sand the Body Filler

Once the body filler has dried and hardened, use 180-grit sandpaper to sand the area until it is smooth and even with the surrounding metal. After achieving a smooth surface, switch to 400-grit sandpaper for a final, finer sanding.

Step 9: Clean the Area

Using a microfiber cloth and paint thinner, clean the area around the windshield to remove any dust, debris, or residue from the rust removal and repair process. This will ensure proper adhesion of the primer and paint.

Step 10: Apply Automotive Primer

Mask off the surrounding areas of the vehicle with painter’s tape and plastic sheeting to protect them from overspray. Apply a layer of automotive primer to the repaired area using a paintbrush or paint sprayer, following the manufacturer’s instructions for proper application and drying times.

Step 11: Sand the Primer

Once the primer has dried, lightly sand the area with 400-grit sandpaper to ensure a smooth surface for the paint application. Be sure to clean the area again with a microfiber cloth and paint thinner to remove any dust or debris.

Step 12: Apply Automotive Paint

Apply the automotive paint to the repaired area, using a paintbrush or paint sprayer, and following the manufacturer’s instructions for proper application and drying times. Apply multiple thin coats, allowing each coat to dry before applying the next.

Step 13: Apply Clear Coat

After the paint has dried, apply a clear coat to the repaired area to seal and protect the paint. Follow the manufacturer’s instructions for proper application and drying times. As with the paint, apply multiple thin coats of clear coat, allowing each coat to dry before applying the next.

Step 14: Wet Sand the Clear Coat

Once the clear coat has dried, wet sand the area using 1500-grit or higher sandpaper. This will help to create a smooth, even finish and blend the repaired area with the surrounding paint. Be sure to keep the sandpaper wet throughout this process, as dry sanding can damage the clear coat.

Step 15: Buff and Polish the Repaired Area

Using a buffing compound and a polishing pad, buff the repaired area to restore its original shine and blend the new paint with the existing paint. Work in small, circular motions, applying even pressure throughout the process.

Step 16: Clean the Area

After buffing and polishing, use a microfiber cloth to clean the area, removing any residue or dust from the repair process.

Step 17: Reinstall the Windshield (If Removed)

If the windshield was removed for the repair, reinstall it using a fresh bead of auto glass sealant. Follow the manufacturer’s instructions for proper application, ensuring that the sealant forms a continuous, airtight seal around the perimeter of the windshield. Allow the sealant to cure according to the manufacturer’s recommendations before using the vehicle.

Step 18: Inspect the Repair

Inspect the repaired area to ensure that the rust has been effectively removed and that the paint and clear coat have blended seamlessly with the surrounding paint. If any imperfections are present, repeat the necessary steps to achieve a satisfactory result.

Step 19: Maintain Your Vehicle

To prevent future rust development around the windshield or other areas of your vehicle, regularly inspect and maintain your vehicle’s paint and protective coatings. Address any signs of damage or wear promptly to protect the underlying metal from corrosion.

Step 20: Educate Yourself on Rust Prevention

Stay informed about the best practices for rust prevention, including proper washing and waxing techniques, prompt repair of chips and scratches, and the use of rust inhibitors. By taking proactive steps to protect your vehicle from rust, you can help to extend its life and maintain its appearance.

By following these steps, you can successfully repair rust around your windshield and restore your vehicle’s appearance. Regular maintenance and proactive rust prevention measures can help to protect your vehicle from future rust development and prolong its life. If you are unsure about any aspect of the rust repair process or need assistance, consult a professional auto body technician for guidance.
