It’s no doubt that sanding a clear coat can create finer scratches on painted surfaces, which you can polish later to make the surface smoother. Thankfully, that will help not only protect the paint on your car but also give it an exceptional outlook.

Sanding a clear coat can seem challenging, but it’s not. While the entire process might take a considerable amount of time, you must do it with a lot of patience and attention.

How to Wet Sand Clear Coat

During painting, an orange-peel effect can occur on the car’s surface. As a result, an imperfect bumpy surface may form. However, the amount of orange peel formed will depend on either the paint’s thickness or how you apply the clear coat.

To achieve a glossy shine on the car, you have to remove the orange peel by sanding the clear coat. Once you’ve applied the fresh coat, leave it for 24 hours to harden. It is only after the clear coat has set so that you can go ahead to sand and buff.

You may be wondering if sanding a clear coat is something that you can handle; then, the absolute answer is yes.

All you require to start the process is a quality grade auto-body cleaning solution, a spray detailer, water, a bucket, towel, rag, two different sandpaper grades one (600 and 1200 grit), a tape, and a buffer.

The whole sanding process takes place in the following three phases.

  1. Cleaning and soaking
  2. Sanding the surfaces
  3. Buffing the sanded area

Cleaning and Soaking

Here are the steps to follow when cleaning and soaking the surface for sanding.

1.  Cleaning the Exterior of the Car

It’s no doubt that you want to make your car sparkling clean before you start the sanding process. So, focus on removing any dirt and stain present during cleaning. Use plenty of water and a car-washing detergent to reach the coat with ease.

The wet rag will keep the surface moist throughout the process. You don’t have to keep the car surface soaked, but make sure it never goes dry as you sand.

Sanding the Surfaces

Now that you’ve cleaned and soaked the clear coat surface, the next step is to sand it.

1.    Sand Small Sections at a Time

If you want to come up with even levels, choose a section that you manage to sand. For instance, you can sand a small area at a time. Let’s say one square foot. Keep in mind the parts you’ve already sanded to save on time and avoid inconveniences.

Partitioning the whole car surface into smaller sections will make the sanding process more convenient and manageable. Besides, each partitioned section will receive equal attention. In other words, that will ensure that the surface gets sanded uniformly.

2.    Start Sanding

When wet sanding the clearcoat, replace the orange peel with finer scratches to smooth the entire surface. To achieve better results, start sanding using the 600 grit sandpaper. Later on, you can use the 1200 grit sandpaper to get quality results.

3.    Use Proper Sanding Technique

Before you sand, apply masking tape on the delicate surfaces to prevent them from getting scratched. After you have taped, be free to sand at 45 degrees to get rid of the marks.

Similarly, sand with long strokes on the direction of the wind. Evaluate the sanding progress regularly to ensure that it’s smooth and uniform.

4.    Change the Sanding Direction

Occasionally, change the direction of sanding using faintly diagonal directions from the previous strokes. Move all through the whole surface systematically and ensure you sand the entire surfaces.

To prevent the coat from burning, keep the surface wet over and over again. Ensure the change in direction is uniform to pull off a smooth level.

Carefully buff through the surface and ensure uniform distribution of the polish. To prevent the paint from burning, regulate the amount of compound you put on the buffing pad. When done, wipe off all the buffing compounds remnants.

3.    Carry on Buffing with a Soft Pad

At this stage, it’s evident that the surface is turning out positively. The scratches are wholly covered, and the bumps are no more.

Using a finishing polish and a soft buffing pad, keep buffing until you attain a shiny surface. During this phase, the buffer can run at a higher speed with no possible damage.
