Everything looks fine on your vehicle until that day when rust decides to show up. Exposed to heat and cold, moisture, dirt, sludge, and water, it's only a matter of time before rust starts to develop and eat away at the metal underneath. If your vehicle's windshield frame is contaminated with rust, don't just sit there to wait and see what will happen next. Before rust extends to other parts of the car, remove it from the frame of your windshield. This can turn into a bigger problem if you don't deal with it fast enough. You may have to buy a new frame if rust starts to spread all over, leaving you with corroded metal underneath. The structural integrity of the frame holding the windshield can be compromised. But don't worry; we'll help you figure out how to remove rust. Here's a step-by-step guide.

Needed tools and materials:

  • Pry tool
  • Utility knife
  • Sponge
  • Sandpaper
  • Detergent, cloth
  • Denatured alcohol
  • Oscillating sander
  • Bondo
  • Putty knife
  • Rust-inhibiting automotive paint
  • Self-etching primer

Step 1: Remove the windshield. You can have this removed by a professional. But if you're up to the task, then here's what you have to do. First, take out the windshield wiper arms. Once these are detached from the windshield, get your pry tool to set the rubber seal loose and pull it out from the windshield. Next, use a utility knife for cutting around the urethane seal. When the seal is already cut off from the perimeter of the windshield, you can now remove the frame by pushing it out carefully. You may need someone to help you with this. Set aside the windshield you just removed in a safe place.

Step 2: Clean the windshield frame. Use warm water and detergent for washing the frame. With a wire brush, scrape rust off it. Once rust is removed, move on to sanding the rusted areas using an oscillating sander. For areas on the frame that are heavily rusted, use 60- to 80-grit sandpaper. For minor rust, use 120-grit sandpaper. Sand off the rusted areas of the frame until you get to the bare metal part. After sanding, wipe the frame clean with a cloth and denatured alcohol until there's no more grease and other contaminants left.

Step 3: Fix the small holes and other rough spots on the windshield frame using Bondo. This should be applied with putty knife. Leave this to dry and harden for about 45 minutes (check the label to be sure). After this, you have to sand the damaged area you've just fixed using 120-grit sandpaper. Continue sanding until the surface becomes even and smooth.

Step 4: Spray multiple coats of automotive self-etching primer on the windshield frame. For best results, the nozzle must be 8 inches above the frame when spraying the primer. Let it dry before you add another coat.

Step 5: Coat the frame with several layers of rust-inhibiting automotive paint.

Step 6: Put back the windshield on the windshield frame and seal this with a rubber gasket.
