What Types Of Grit Sandpaper Can We Use For Wet Sanding?

The grit of sandpaper is the number of abrasive particles per square inch of a sandpaper sheet. Fewer abrasives are present as the number decreases, resulting in coarser sandpaper. The greater the number of abrasives, the finer the sandpaper.

  • 40 to 80 Grit — This grit of sandpaper is quite coarse and can leave noticeable markings, thus it is not suggested for minor clear coat scratches and other comparable applications. Instead, it is indicated for rough sanding before bodywork and for shaping body filler.
  • 120 to 180 Grit — Use this grit range to smooth off scratches, feather the edges of body filler, sand small areas of putty, and remove light rust.

This range of grit is substantially more delicate than those previously stated. It is suitable for pre-primer sanding, rough primer sanding, spot putty sanding, and final body filler sanding. Also advised is the use of a sanding block.

  • 600 to 800 grit sandpaper is ideal for removing primer surface defects before painting.
  • 1000 to 1200 Grit – This grit range is ideal for removing base coat flaws. Use the wet sanding method for optimal results.

This is the grit range to use when we need to remove surface flaws and scratches before and after applying the clear coat. It will also need the wet sanding approach to avoid sandpaper clogging.

The Process Of Wet Sanding A Car

Step 1

The sort of damage we are attempting to repair will determine the sandpaper we will use. If we are repairing minor damage or wet sanding a new automobile, use 2000 or 3000 grain sandpaper. To remove deep scratches, use sandpaper with 1200 or 1500 grit.

Step 2

Now, split the sandpaper in half lengthwise. Cut the paper so that it may be wrapped around a sandpaper block or pad. Then, fill a bucket with water and add car wash soap..

Step 3

Before we begin wet sanding the vehicle, remove any dirt or debris from the working area by washing it. Utilize a cleaning mitt and vehicle wash solution to eliminate the blemish, then utilize microfiber towels for drying.

Step 4

Sand the affected area with the sandpaper wrapped around the applicator. We should not rely only on our hands since doing so might result in an uneven finish. Use the applicator in a gentle circular motion on the selected area.

Step 5

Using sandpaper in different directions produces a smooth surface. Ensure that we do not alter the pressure while changing direction. Also, avoid letting the sandpaper dry up. Repeatedly dip it in the soapy water.

Step 6

Rinse the area with water to eliminate debris. Park your vehicle in a shady location and let the spot dry. Do not dry the automobile by parking it straight in the sun.
