Best Bauschaumpistole I had so far in use. Have processed already ne more on expanding foam in my new building but this one is definitely the best. Does it very well dosed, remains absolutely clean normally soiled very quickly and at the nozzle. It is to die and still can receptacle absolutely tight after I've processed over several days DOCHEN. After working through cleaner or if a two-day working later can be easily foam can be screwed. Very good seller service in question. Thanks to Arbeitsbedarf24
