Repair Auto Body Rust

Rust is often an automobile's worst enemy. Rust can appear less then 24 hours after a scratch or ding cuts through the painted finish to reveal the bare metal surface of the car. The rust the spreads under the paint so you can't even see the extent of the damage until you notice paint bubbling and flaking off. Learn repair auto body rust before it spreads and eats away at your car's body panels.


Instructions


1. Locate all of the rust on your car's surface. Use a grinder to grind away all of the visible rust. Continue grinding the paint around the area of rust so that there is an area of bare metal about 3 inches away from the outer edges of where the rust was removed.


2. Apply a thick coat of body filler directly to the area where the rust was removed. The body filler will fill small holes where the rust may have gone through the metal. Allow the filler to dry completely.


3. Sand the body filler with a long sanding block and 36-grit sand paper until the filler is smooth with the surface of the car. Apply a thin coat of putty over the filler and allow it to dry. Sand the putty with 80-grit sand paper on the sanding block. Cover surrounding areas not intended to be painted with masking tape and paper.


4. Spray the entire area, including the bare metal area, with three coats of automotive primer. Allow each coat to dry. Sand the top layer of primer with 120-grit sand paper and a long sanding block to smooth the surface.


5. Apply four thin coats of automotive paint to cover the primer. Allow each coat to dry completely and then spray four coats of clear coat on top of the paint.
