How To Fix Rust Spot On A Car

A rust spot on the body of a car will continue to spread until it is removed. If you encounter a rust spot, it is important to deal with it swiftly to ensure that it doesn't have the opportunity to become a larger issue. Here is a step-by-step guide on how to fix a rust spot on the body of a car.

You will need the following tools to complete the job:

-One hand sander

-Metal grinder


-Painter's tape

-One can of primer

-One can of paint

-One can of Bondo

1 - Start by grinding off the rust as much you can with the metal grinder. Grind around the edges of the rust spot as well and about an inch into the paint job from where the rust begins. This will ensure that you remove any rust that is in the beginning stages of taking root in the body.

2 - Once the rust has been ground out, take the hand sander and sand paper and smooth out any rough edges left by the grinder. Sand the entire area that will eventually need to be painted until it is completely smooth to touch by hand.

3 - Once the area is smoothed out, take the can of Bondo and apply it to any holes in the body of the car left by the rust. Apply the Bondo over the entire area that was previously rusted over and make sure that it is smoothed out. Once the Bondo has been applied, let it dry for a full twenty-four hours before proceeding to the next step.

4 - Once the Bondo has dried, use the hand sander and touch up any rough edges. Again, make sure that the surface area is completely smooth to touch before you start painting.

5 - Apply a coat of primer paint over the entire surface area that has been worked on so far. For darker colors, you may require a second coat of primer paint before you have enough to cover the metal from showing through the primer.

6 - Take the paint and apply it over the primer, paying careful attention to match the color of the rest of the car. Let the paint sit to dry for twenty-four hours, and re-apply another coat if necessary to complete the job. When you buy the paint, you may want to consult with a auto body paint specialist like Collision-One, Inc. to match the color of your car correctly.

Following the tips outlined above can help you fix a rust spot on your car. If  the above steps do not fix the problem, it could be a sign that you have a much larger problem, and you should consult with an auto body specialist to have the problem fixed by a professional.
