Hail Dent Repair Australia repairs anything from private work dents to door dints, car park dents or trolley dents. Dents can also occur when someone closes a bonnet or boot heavy handily and puts a dent on the panel. They can also occur on fuel caps. since 2020, it seems the metal gauge or thickness/strength of the panels have become thinner and therefore weaker. So dents such as these are not surprising.
