The ice will melt away safely without damage to the glass.

Dents that are not thoroughly repaired are often filled with polyester resin or fibreglass paste. Tap the surface, or go along it with a magnet. Know whether the panel is made of steel, not plastic, fibreglass or aluminum. If there are places where the magnet will not adhere, then in all likelihood, the panel has been repaired. Ask the owner why the part has been repainted?
