How to Remove a Chemical Burn in My Car Paint

One of the most noticeable issues on a vehicle is damaged car paint. Car paint can be damaged by chemicals, salt, bird feces (bird poop), eggs and sap. If you leave bird feces, smashed love bugs, egg, or sap on your car paint for too long, it can damage the finish, resulting in staining and pitting. Driving through road construction areas can leave tar splatters that appear to leave a burn and damage the paint. As much as possible, avoid situations such as road construction areas, or parking under trees or buildings, that allow corrosive and acidic materials to land on your car.

Things You'll Need

  • Auto cleaner
  • Wax removing solvent
  • 1000 grit fine sandpaper
  • Bondo
  • Primer
  • Autobody paint
  • Autobody gloss
  • Paintbrush
  • Wax or finishing compound
  • Clean the automobile and spots immediately after any chemical, or potentially acidic or corrosive material, lands on your car paint.

  • Apply a specially-formulated cleaner or solvent that will remove wax on the chemical burn areas.

  • Sand the spot of the chemical burn with 1000-grit, fine sandpaper. Keep the sanding area tight around the burn to avoid scratching, or removing the finish beyond the burn, more than necessary.

  • Apply bondo compound to the chemical burn, if the burn pits below the paint layer into the car body.

  • Sand the area with bondo on 1000-grit, fine sandpaper after the bondo dries.

  • Apply one or two layers of primer, then two to four layers of auto-body paint, using a small, soft paint brush from an auto-body paint repair kit. Allow each layer to dry completely as the manufacturer recommends. Sand between primers and layers as the manufacturer recommends (dry sand or wet sand may apply). Then apply the recommended coats of clear coat.

  • Buff and wax the entire car's paint job to finish repairing the chemical burn or pit in your car paint.
