I accidentally drove my car over a curb a while back. As you probably already know, the car suffered from minor scratches and dents on the bottom side, near the rear tyre. Now, I've noticed that it's now slowly developing rust on the scratched paintwork. The rust isn't too bad, i.e. the rust part still feels pretty solid.
How do you effectively deal with this kind of problem (other than telling me to drive more carefully)?
The best thing to do would be to sand down the rusted area until you can see the original metal and then apply a automotive primer to protect it from the rust.
If you feel pretty comfortable with a bottle of spray paint and aren't too worried about a pro job, you could then obtain some automotive spray paint and repaint the affected area(s).
One thing to keep in mind is that you're going to want to sand down the smallest area possible. When priming and painting, cover exposed surfaces with newspaper and tape it down so that you don't end up with primer or paint running on other surfaces of your vehicle.
I used Napa Rust Treatment Permatex 765-1671 on my F-150 truck about 8 months ago and all the rust is gone! This treatment is like a grey primer. It's not pretty on a blue truck, but neither is oxidized red cancer.
