Cold shrinking

Cold shrinking is a process in motor vehicle bodyworks.[1] Compared with hot shrinking, cold shrinking is a longer process, but it is the most preferred method and most common especially where the stretched area is bigger.[2] Cold shrinking is mostly done by use of a dolly hammer.[3] The rough surface is the fill using a body filler or a body solder in order to give a smooth finish.[4]

This is a method of panel beating where heating is not done to the stretched panel. This method is mostly suitable for integral cars with integral body panels such as hatchbacks..[3] [5]
