A characteristic feature of this putty are its multifunctional properties, i.e. the capacity of application on virtually all substrates encountered in body coating; good performance in filling small and large decrements, easy application at elevated temperature and high surface smoothness, good sandability with fine and coarse sand papers, and the hardness selected to retain the desired profile during sanding. The high reactivity of the putty ensures a short time to proper hardness for sanding at low temperatures and reduces the time of work.
