How to fix a dent in hard plastic?

[VonDaniela]

You can use a lighter with aluminum foil or a hair dryer to heat the area until it softens, then push it out from the inside with your fingers. You can also use a plunger coated with Vaseline around the edges, place it over the dent, and pull hard to remove the dent.

Last time there was a small dent in the hard plastic dashboard of my car, which looked quite upsetting. I tried using a hairdryer to blow hot air for a few minutes to soften the plastic, then gently pushed it back from the inside. After cooling, it became smooth again. A suction cup also works—just align it with the center of the dent and pull to reset it. Regular maintenance is key; avoid hitting plastic parts with hard objects and park in the shade to prevent heat-induced aging. This method is effective for shallow dents, but be careful not to heat the plastic for too long, as it may deform or crack. For severe dents, it’s safer to seek professional repair.
