I've done a touch-up of some scratches on my paint, and a couple of drips went on the matt black bumper. I tried to wipe it off but there is still some residue. Tried WD40 on a microfibre cloth, to no effect. I have some leftover T-Cut style stuff from a headlamp restoration kit, would that work?

  • What is the bumper material ? Is it painted / Commented Nov 4, 2021 at 14:59
  • It's black plastic, matt texture.

  • Experiment on a small area of the bumper that can't be seen, like the underside. Commented Nov 4, 2021 at 17:46

Because it is solid black plastic, an abrasive will remove it. something like 400 grit should make a matte surface ; you will need to practice, to much rubbing or too fine a grit will produce more shine -less matte. PS; My black plastic bumpers were yellow urethane under the paint.
