Rubbing compound is a material used to restore old paintwork, and it acts as a new top coat for your car. In addition, it also helps conceal scratches in your car's paint. First, wash your car thoroughly with soap and water. Then, use sandpaper and an orbital polisher to smooth down existing scratches. You can easily apply your rubbing compound with either a polisher or microfiber cloth to bring dull or damaged paint back to life!

Washing Your Car

  1. To wash your car, it is helpful to prepare a soapy mixture. Washing your car removes any loose dirt, dust, or mud. You should always use car washing soap or conditioner so you do not damage your paint. Squeeze a bit of soap into a bucket, and use a hose to fill it with water. [1]
    • If you are removing scratches, washing your car lifts up any excess dirt. This makes it easier to see all your scratches clearly.
  2. Submerge your rag so it is saturated in your soapy mix, and rub it over all of your car, starting at the top. Move your hand in a circular motion to lift up dirt and debris. Cover your car in soapy bubbles so it is completely clean! [2]
    • As you wipe your car down, dip the rag back into your bucket to use fresh soap mixture.
    • If your water gets black and murky, replace it with a fresh batch of soap and water.

  3. Hold your hose about 2–3 ft (0.61–0.91 m) away from your car, and let the water spray over the surfaces of your vehicle. Wash off the entirety of your car, so there is no remaining soap residue. [3]
    • You can park your car in a sunny spot so it dries quickly, if you'd like.
    • Don't wait too long to rinse the car, or the soap might dry on the surface, leaving marks. [4]

Repairing Any Paint Scratches

  1. You cannot remove the scratch, but you can sand down the paint around it to make the scratch invisible. Take another clean rag, and wipe up 1 small dollop of shoe polish from its container. Shoe polish makes it easy to see the scratches, so you don’t sand too far beneath the scratch.
    • Washing your car makes it easier to see any and all scratches on your car.
    • Use black shoe polish if your car is a bright color.
    • Use white shoe polish if you have a dark-colored car.
    • If you don't have scratches on your vehicle, this is not necessary.
  2. Dip a clean rag into your soapy water, and ring the rag out over top of your scratches. Adding a bit of water helps lubricate the area, making it easier to repair scratches in your paint.
    • If your water is dirty, it is best to mix up fresh soap and water. That way, you do not add any additional scratches to your car.
  3. Place your sandpaper on a wooden block so you have a flat edge to sand with, and hold it in place. Tilt your sandpaper so it is at a 60-degree angle at your scratch, and use light strokes in a back-and-forth motion.
    • Remember, you want to sand the paint around the scratch. Look for the mark of shoe polish, and sand directly next to it.
    • For best results, use 2000-3000 grit wet/dry sandpaper.
    • Do this if you are repairing paint scratches.
  4. To make the process easier and quicker, it is helpful to lubricate your sandpaper with your soapy water. Dunk a piece of sandpaper into your bucket, then rewrap it around your wooden block. Sand back over your scratched areas until all of the shoe polish vanishes.
    • You can sand down the paint initially with dry sandpaper, then wet your sandpaper to smoothen over the surface. This makes it easier to fix scratches.
    • If you find any additional scratches on your car, sand over them at this time.
  5. After you’ve sanded over all of your scratches, turn on your hose, and run water over your rag. Rinse off any residual soap, and ring out your rag when finished. Then, use the rag to wipe away any paint debris or dust.
    • You can move your hand in wide, circular motions over your entire car.

Applying the Rubbing Compound

PDF download Download Article
  1. To most effectively apply your rubbing compound, you can rent or buy an orbital polisher from most home supply stores. When rubbing compound over the entire car, use a soft pad.
    • On average, a polisher costs about $30 - 70 to buy new (£21.30 - 49.71).
    Dennis W. Parks, Automotive Repair Expert

    Rubbing compounds contain mild abrasives that safely remove minor defects from automotive paint finishes without removing large amounts of clearcoat. Selecting the right grade of rubbing compound is critical — heavy-cut formulas rapidly remove deeper scratches but leave behind visible swirl marks if not properly finished, while fine-cut compounds provide a high-gloss finish.

  2. While orbital polishers do the best job of spreading the rubbing compound, you can also effectively use a towel. [5]
    • Make sure your towel is completely clean so you do not rub dirt and debris into your car.
    • Do this if you don't have access to a polisher or want to remove scratches on a budget.
  3. You want the scratched areas to be covered with rubbing compound. If your compound comes in a tube, you can squeeze it directly onto the scratches. If your rubbing compound does not come in a tube, you can scoop some out using a paper towel or rag.
    • Rubbing compound helps smoothen over the freshly sanded areas, so your scratches look invisible.
    • Make sure your car is not in any direct sunlight before you apply the compound.
  4. Use a wool pad if you are using a polisher. Place your polisher directly onto the scratch, and pull the trigger or press the button to start the machine.
    • The orbital polisher will rapidly spin across the surface of your car, spreading the rubbing compound over the scratches.
  5. Apply about 1 teaspoon (4.9 mL) of compound to your cloth or polisher after you spread rubbing compound over the scratched areas. Start at the top of your car and apply the compound in 1–2 ft (0.30–0.61 m) sections. Move your hands or the buffer in a circular motion to apply the rubbing compound. [6]
    • In addition to removing scratches, rubbing compound freshens up the color of your car and makes it look sparkling and shiny. It essentially acts as a polisher for your car.
  6. Move your orbital polisher or microfiber cloth in small circles until you rub in all of the compound. Press into the surface of your car with moderate force as you apply the compound. The compound is completely rubbed in when you cannot see any residue or streaks on your car. [7]
    • With moderate force, your rubbing compound should disappear in 1-2 minutes, on average.
    • Check to make sure all spots are shiny and beautiful when you are finished. You can go back over any areas you missed at this time.
  7. Stand with your hose about 3 feet (0.91 m) away from your car, so you can evenly spray water over your vehicle. This washes off residual compound and any dirt or dust that was lifted up. [8]
    • Once your car is rinsed, it is helpful to let your car dry thoroughly in the sun.

    Yes, but it will take a lot of effort to get the same results you would with an orbital buffer. Use firm pressure and buff the compound in using a clean microfiber towel, using clockwise circular motions. Wipe away the compound by buffing it again in the opposite direction using another microfiber towel. Always work in a shady area so the compound doesn’t dry out too quickly while you’re working.

    It can be if you aren’t careful. Before using rubbing compound, try using less aggressive techniques to touch up minor imperfections. For instance, a gentler polishing compound may do the trick, and it’s less likely to strip away the actual paint or the protective clear coat on top.

      About This Article

      Article Summary X

      To use a rubbing compound to restore your car’s old paintwork, first wash your car and smooth down any scratches. When washing your car, dip a clean rag in soapy water and work in a circular motion to remove any dirt or debris. If you have any scratches in the paint, use ultra-fine sandpaper to buff them out. Then, use an orbital polisher or apply the rubbing compound by hand. Start by putting a thin line of the compound directly over your scratches, and apply a small amount to your rag or polisher for the rest of the car. Rub the compound into the surface of your car until it’s invisible. To learn how to rinse your car after applying the rubbing compound, keep reading!
