How self-healing PPF works

Short answer

Self-healing PPF has a flexible topcoat that “remembers” its smooth shape. When light swirls or scratches mark the surface, heat from the sun, warm water or a heat gun lets the topcoat flow back into place and the marks disappear. It works on marks in the topcoat, not on cuts that go through the film.

How it works

The topcoat is made from an elastic polymer. A light scratch pushes it out of shape without breaking it. Warmth softens it enough to relax back to its original smooth surface. Polyshield’s topcoat is heat-activated, so the warmer it gets, the faster marks fade.

How to heal marks

  • Park in the sun. On a warm day, light swirls often fade within hours.
  • Pour warm water over the area.
  • Use a heat gun on low. Keep it moving and well back from the surface. Best left to an installer if you’re unsure.

What it won't fix

  • Cuts or gouges that go through the film.
  • Chips from large stones that tear the film.
  • Dents or damage to the panel underneath.

In those cases the film did its job: it took the hit instead of your paint. The damaged section can be replaced by an installer.
