How To Fix Rust On A Car

Anyone can easily learn how to fix rust on a car. Though fixing rust on a car may take some time, it is less expensive then taking your car to the shop and you get the satisfaction of self-efficiency.

To fix the rust on a car, you will need:

• A smooth 120 grit sander
• Automotive metal primer
• Automotive paint matching your car's color
• Automotive body filler
• Masking tape

1. Examine the rust on a car body. Make sure you can reach all of the affected area before you start sanding. Remove any parts that are blocking your way to the rust on a car, such as trim, and start sanding the area with circular motions.
2. Sand evenly and sand the paint off a one inch area around the rust. By sanding and removing paint off of a small area around it, the repaired area will blend in better once painted. It's important to clear away all the rust residue before you prime or paint, or it might show under the paint when you are done.
3. If the rust was really bad and the sanded area is indented slightly, you will want to use auto body filler. Make sure the area is clean and apply the filler, following all instructions on the container. Allow the filler to set, checking the hardness by gently pressing your thumbnail on the filled area.
4. Once dry, sand the area with the 120 grit sander again to smooth it and make it blend in. You are ready to prime.
5. Use the masking tape and tape over any near parts near the repaired area that aren't the same color, such as grilles or door trim. Spray on two to three layers of primer, waiting three minutes in between layers.
6. Next, spray on three to five thin coats of paint. Allow the paint to dry for 24 hours. Applying thin coats and letting them dry for fifteen minutes keeps the paint from running or dripping. Remove the masking tape and examine your handiwork.
7. Wash and wax the car for best results.
   

Now you know how to fix rust on a car, but to prevent rust altogether you will want to use a rust preventive treatment on the metal before you paint it. Always wear a face mask and protective eye gear when sanding.
