How To Remove Rust From An Oil Field Truck

How To Remove Rust From Oil Truck

Rust happens, and when it does it’s important to address it as quickly as possible before your entire truck falls apart. Oil field trucks can be particularly susceptible to rust, if only because of their size and the amount of wear they get. You can remove rust and prevent damage safely with these directions.

Supplies: Everything You Need

  • Gloves
  • Dust mask
  • Safety glasses
  • Painter’s tape
  • Masking paper
  • DA sander
  • 80 to 150 grit sanding attachments
  • Metal grinding wheel
  • 400 grit sandpaper (loose)
  • Paint thinner
  • Metal primer
  • Auto spray paint
  • Rag

Instructions — Step-by-Step

  1. Put on gloves, glasses and dust mask. The process of getting rid of rust will kick up metal filings into the air, which can be very dangerous if inhaled.
  2. Using painter’s tape, tape masking paper around the rust spot that is to be repaired, making sure that there is a solid seal of tape around the portion to be painted. This will prevent any damage where the paint has not rusted over. Leave around four to six inches of room on either side of the rust spot; you need enough room for the sander.
  3. Use your dual action sander to slowly buff away at the rust spot, beginning at 80 grit. Make sure that you get all of the rust.
  4. If you cannot get all of the rust out with 80 grit, use your metal grinder attachment to get the last remnants.
  5. Slowly begin buffing the surface in higher grades of grit until you reach 150 grit.
  6. Smooth the surface that you have just sanded with loose 400 grit sandpaper. At this point, it should be clean and with a dull shine.
  7. Wipe down the entire surface with paint thinner to remove excess metal filings and to prepare the area for paint.
  8. Spray the entire area within the painter’s tape with spray primer. Wait for three to five minutes and then repeat three or four times, until you have a thick and even coat of primer.
  9. Allow the primer to set for at least 12 hours, or overnight.
  10. Sand the primer in the morning with 400 grit sandpaper, until it is dull and the entire surface is even.
  11. Using a wet rag, wipe off any dust from the primer and then allow to completely dry.
  12. Spray the entire area within the painter’s tape with automotive paint. Make sure that your strokes are thin and even. Do not try to coat the vehicle too much at any time, as this will cause dripping.
  13. Wait three to five minutes and repeat the process until the paint is even and opaque.
  14. Allow the vehicle to dry for at least a day.

The paint, along with the primer, will help protect the vehicle from future rusting. Though you could simply sand the rust off to remove it, the vehicle would likely quickly rust again as the metal would be exposed to the elements. With an ordinary vehicle, you would likely jump through some hoops to ensure that the paint is the exact same color of the car–with an oil field truck, all that matters is that it does the job right.
