4. Updated September 2011 Many spend hours washing, waxing and buffing the paint so the vehicle looks the best it can be—shiny and new. A scratch on the paint of this revered automobile leads to great disappointment. What if there was a product that when applied to the body of the car would protect it from scratches and the weather? Well, now there is!

6. Updated September 2011 Typically, when car wax is applied to the car and buffed, it creates a shine that is permeable. The new waxes that have been created using nanotechnology seep down into invisible holes in the body of the car. The particles in the nanotechnology wax are so small that they allow the wax to penetrate the miniscule holes in the body of the car. Therefore, scratches and minor dings can simply be wiped away.

7. Updated September 2011 In the activity, you will lightly scratch an auto body part with 400 grit sandpaper. Then you will test a nanowax against an ordinary wax to see which fills light scratches better. Image by HighPoint Learning

8. Updated September 2011 Get a used auto body part from a repair shop. Repair shops recycle all the old dented parts for scrap and will probably give you one. Label several places on the part to take before and after photos.
