It's time to get that rust off.
There's nothing like a peeling paint job and spots of rust to make your ride look trashed. While you could paint over the rust, that wouldn't fix the damage, so the best thing to do is sand down the rust and re-paint. Sanding down that rusty car will take a long time and give you a good workout if you do it by hand, or you can make the job easier with a sandblaster.
Instructions
1. Strap on a face mask before you start. You'll be creating a lot of dust and paint particles and you don't want to breathe them in.
2. Fit your power sander with 80-grit dry sandpaper to begin. This grade should remove most of the paint so you can get to the rust.
3. Bring the power sander up to the surface of your car. Then turn it on low or medium low. Work the sander back and forth across your car's paint until all or nearly all of the paint flakes away and your car is down to bare metal. Wipe away any paint flakes with your cotton cloth so you can better see the car's condition.
4. Work across all areas of your car in this manner. Before you can treat the rust, you need to get the paint off. Switch to the 40-grit sandpaper and work the power sander over stubborn areas to remove paint that didn't already come off.
5. Spray the metal with an anti-rust spray to prevent the rust from growing back.
6. Apply a coat of primer to your car using an aerosol spray primer. Your car is vulnerable in its bare metal state, and the primer will protect the auto body until you have time to paint.
