How To Polish Your Car With A Drill Step by Step
Step 1: Prepare Your Drill
Before you start polishing your car with the drill, make sure that you have everything you need.
Replace worn-out parts immediately to avoid accidents. Replace old brushes, old or leaking batteries and damaged cords. Make sure that your drill is in good condition before using it to polish your car.
However, if your drill is working well and this is the first time you intend to polish a car with it then you can skip this step and go straight on to step 2 below.
Step 2: Choosing The Sandpaper
To begin with, choose an abrasive paper in between 120 and 200 grit in accordance with your drill’s capabilities and load it into your drill. You can either buy pre-loaded sandpaper, or you can choose the one that’s best suited to your car.
Step 3: Keeping Your Car Dry At All Times
When using a drill to polish a car, avoid water and wet paint. If the paint gets wet then it will become sticky and will make your car look worse than before. Apply some oil on the surface of your car after it has been thoroughly dried using a cloth that has been thoroughly dried.
Step 4: Start Polishing
Now, you can start polishing your car using the drill. Begin with an area that is less sensitive than others. You can start polishing from the cabin and move your way to the boot lid.
Always hold your drill straight and polish evenly with little pressure.
Step 5: Buffing With A Clean Cloth
After some time, you can switch from sandpaper to a clean soft cloth. After each area is polished, wipe it with the cloth. This will add shine and remove the little scratches left by the sandpaper. If you don’t have a cloth, you can use your clean hands while polishing with the drill to remove all the sand particles and polish your car.
Step 6: Repeat Until You’re Happy
It will take some time to polish the car up to your expectation. Be patient.
Reasons Not to Polish Your Car with a Drill
Even I said it’s possible to use a drill to polish a car but there are drawbacks to using it as well.
There’s a common misconception among many people that using a drill to polish a car can actually damage the paint finish. I can tell you that this is normally not the case. But if you do it on purpose then yes, maybe you would end up damaging your paint finish but I don’t think it will affect your car’s performance or safety in any way.
However, there are some incidents where drilling might damage your paint finish. If you drill into a painted surface that is already covered with rust, then it might cause serious damage to your car paint.

Moreover, it’s hard to hold the drill for a long time. You can polish small areas but the whole car is a different story.
