Finally, the sealant at the cracked area is blown and melted with an electric hair dryer. After the natural cooling, the cracked area is repaired. If there is no hair dryer, you can use a flat screwdriver (also known as a screwdriver) to burn the red on the stove, and then directly heat the sealant at the cracked place to repair it.
