Remove Rust From Auto Paint
A rust spot on your car can detract from its appearance and cause extensive damage. What began as a cosmetic issue can turn into a structural one. In time, rust can eat through paint and metal, causing pieces of the car body to fall off. Unsafe, jagged spots remain left behind, presenting a safety hazard and threatening the vehicle's structural integrity. Rust damage can also make a car difficult to sell.
Instructions
1. Use an electric hand-held grinder with a 150 grit sanding wheel to remove rust from your car. This will level the rusted area with the surface around it.
2. Remove the 150 grit sanding wheel from the electric hand-held grinder and attach a metal grinding wheel. Slowly apply the metal grinding wheel to the rusted area to remove the rust from your car. This process should also remove dings and dents from the area. Turn off the grinder and wipe down the area with a clean cloth.
3. Use a piece of 150 grit sandpaper to sand the area by hand. Continue sanding until the formerly rusted surface is completely smooth. When you are done sanding you should be able to close your eyes, run your fingers over the sanded area and not feel any difference between it and the rest of your car.
4. Repair any remaining dents or imperfections with auto body filler, which you can purchase at most auto parts stores. Allow the body filler to dry overnight and sand it with 150 grit sandpaper until it is smooth to the touch and completely level with the surrounding surface area.
5. Mark off the area you plan to paint with blue painter's tape. Apply a thin layer of auto primer paint to the affected area. You can purchase primer paint from most auto parts stores. Allow the first layer to dry for 10-15 minutes. Apply three more thin layers of primer paint. Allow the primer paint to dry overnight.
6. Apply three thin layers of auto paint in the same manner as the primer. Remove the tape and allow the paint to dry completely overnight.
7. Wax the area you just painted to protect it from future rust damage.
