Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an indium alloy. Background technique [0002] Cars are prone to scratches on the surface due to impacts from external forces during driving or parking. Generally speaking, these used defects are divided into three types: (1) Mild scratches. There is an obvious scratch left on the car paint, but it can't be felt by hand, it just damages the transparent layer of the car paint surface. (2) Moderate scratches. The heavier scratches will directly damage the primer layer, and the scratches can be clearly felt. (3) Deep scratches. Deep scratches are heavier scratches that have exposed the sheet metal of the bodywork with a large dip in the sheet metal. [0003] For mild scratches, apply a small amount of fine sand wax or scratch wax to the scratches or a clean towel, and rub repeatedly along the scratches until the scratches are completely eliminated, then polish with glazing wax. ...
