This assembly line I was already known before buying as it was also to buy before the Aldi. The same band, same company just a differently designed packaging for 3,99uro. I desperately needed it now I have it ordered from Amazon at a higher price to the assembly line is worth it. When the user policies followed precisely -to make adherend surfaces absolutely free of grease and clean and also the assembly line at the bond face after no more then touches it sticks so strongly that one it only can be removed mechanically. As I said the top priority is an absolute pre-fat-free cleaning. I use it for many years of the Würth PVC Cleaner Type 20 It cleans as strong as Nitroverdünnung but does not attack plastics. I am totally thrilled by the assembly line and it would buy again.
