How to Remove Rust From Bodywork

The bodies of most vehicles are made of iron. Iron is a corrosive metal, which reacts with oxygen in the air to make iron oxide. The iron oxide then flakes off the surface of the metal, and the process repeats with the next layer of iron. If rust isn't removed properly, it weakens the structural integrity of the iron and spreads to other areas of the vehicle. One small rust spot can take over an entire car if left untreated.

Instructions

1

Use water to clean the area around the rust. Allow the area to dry completely.

2

Use painter's tape to cover the entire area around the rust. Painter's tape will not damage the existing paint on the vehicle's body.

3

Shut the vehicle's windows. If you are working near the engine, use a tarp to cover any exposed areas. If any metal shavings get into the engine, you can have major problems.

4

Use a metal grinding wheel to remove rust from the surface of the area. Start at the top layer and work your way down. Do this until you have removed most of the rust.

5

Use sandpaper to remove the last bit of rust by hand and ensure that the surface is smooth.

6

Clean the sanded area with Stoddard solvent, a mineral spirit. Apply it with a towel and dry it off.

7

Apply the self-etching primer to the area you just sanded. This will seep into the microscopic grooves in the metal and provide a firm hold for the paint.

8

Apply paint over the primer. Or, to avoid an uneven painted look, paint the entire panel.
