Bumper Scuff Repair Part 5 - Buffing

Posted by Jay Schneider. Filed under Automotive.

Most repairs require wet sanding and buffing to blend the repair and render it non-noticeable.  Typically this is accomplished most effectively by following these techniques:

  1. Pre soak, (30 minutes minimum), 1500 grit wet/dry sanding paper in a diluted solution of soap and water. Typically one to two drops of non alkyd soap per 8 ounces of water is all that is needed. This task softens any hard edges the paper may have thus preventing any gouges the paper may inflict into the newly repaired area when sanding.
  2. Mist the repaired area with the diluted water and sand the area lightly. The object here is to rid the area of any over spray and blend the repair into existing paint.
  3. Sand until a uniform surface has been achieved. (SEE FIGURE 1)

Wet Sanding

 FIGURE 1

Once satisfied with the sanding, proceed to polish the affected area by using a polish recommended for removing 1500 sanding scratches, and a white polishing pad. On fresh paint, keep the area wet by misting the surface with 100% water and use light pressure to prevent hot spots and keep the machine rpm’s down to around 1200rpm’s.(FIGURE 2) .

Once satisfied with your results, proceed to finish the area utilizing a black finessing pad, 1200 to 1500 rpm’s, and machine glaze keeping in mind if you do not like to results you are seeing, back up one step – repeat that step and go forward from there. (FIGURE 3),
