Precautions:
When the fender is sunken, it can actually be sucked out with an electric suction cup. First, put the electric sucker in the concave position of the blade, suck it, and then pull it out directly with great force.
Of course, before using the electric sucker, we can use the principle that plastic becomes soft when heated, and heat the sunken part with hot water to improve the efficiency of repairing the sunken part. Finally, after the depression is restored to its original state, it is necessary to use cold water to cool down, thus playing the role of contraction and recovery.
