Special tools, spot welding and mechanical force pulling, are mainly aimed at vehicles with large pits and serious deformation. There is also one kind. Under the condition that the vehicle pit is small and the paint surface is not damaged, the interior decoration can be disassembled and knocked back gently with a rubber hammer from the internal test to avoid secondary damage during maintenance and ensure the original paint of the original factory. The disadvantage is that you have to open the inside! I wish you happiness and hope to help you. Please adopt it in time! thank you
