How to repair a rusty windshield frame

A rusted windshield frame is dangerous because the integrity of the frame is compromised by rust that leads to corrosion and structural damage. The sooner you deal with a rust problem, the easier the job will be. Rust develops gradually, and the more severe the rust, the more difficult the problem. The biggest headache when dealing with a rusty windshield frame is the windshield itself. To completely remove all rust on the frame of a windshield, it is necessary to remove the rubber seal and the windshield.

Step 1

Determine whether you want to remove the windshield yourself or have it professionally removed. Removing it yourself is more profitable, but it is a delicate procedure. Removing the windshield is an essential step in treating rust around the window frame. Remove the wiper arms. Pry the rubber seal loose with a prying tool and remove it from the windshield. Cut the urethane seal around the perimeter of the windshield with a utility knife. Push the windshield out of the frame and store it in a safe place.

Step 2

Clean the windshield frame with detergent and warm water.

Step 3

Scrape loose rust off the frame with a wire brush. Sand rusted areas on the frame with an oscillating sander. Use 60 to 80 grit sandpaper for heavily rusted areas and 120 grit for less severe rust stains. Continue sanding, until bare metal is exposed.

Step 4

Wipe the frame with a clean cloth and denatured alcohol to remove all traces of grease and other contaminants.

Step 5

Repair small holes and damaged areas with Bondo. Apply the Bondo with a spatula and let it dry and harden for 45 minutes. Sand the repaired area with 120-grit sandpaper, until smooth and even.

Step 6

Apply several light coats of auto etching primer to the frame. Hold the nozzle eight inches above the frame while spraying the primer. Let dry between coats.

Step 7

Apply several light coats of rust-inhibiting automotive paint to the windshield frame. Rust inhibiting paint is available at local auto parts stores.

Replace the windshield and the rubber gasket on the window frame.
