Sandblasting your car can remove rust stains and help prepare your car for new paint. However, you must choose the sandblasting media carefully; the wrong media may damage the metal panels of your car, causing small dents or other flaws. When sandblasting rust away, a good rule of thumb for media is to start gentle and step up.

Gentle

When sandblasting rust, the safest way to remove rust without damaging the rest of the material is by starting with the softest sandblasting media available. One advantage to using abrasive sandblasting to remove rust instead of chemical cleaners is the lack of harsh chemicals and pollutants involved in sandblasting. For gentle rust sandblasting, ground walnut shells are a soft and environmentally friendly sandblasting option.
