What to do if my car is rusting?

If you confirm that your car has some patches of rust, whether this is very severe or just starting, you have some options to choose from, including the following:

1.      Use rust removal kits

Depending on the severity of the rust, you might be able to get rid of the rest of yourself. There are plenty of available commercial kits and many good components that are easy to use and don't need any professional experience.

4.      Replace impacted parts

If the rusted area is not repairable and your mechanic or the professional indicates that there is no way you can fix it, we still hope to replace the part. For example, say that a door within your vehicle is impacted by rust. You can remove that door and replace it with a different one, assuming that repair costs are insignificant.

5.      Sell your car
