You can find it everywhere in advertising brochures and TV commercials: ALL-PURPOSE Glue.
As an inclined customer, the name suggests to me that I can glue anything together with these super products. For instance, a selected advertisement from a well-known manufacturer states: “The All-Purpose glue glues many materials together, quick and long-lasting.”
Yes…however, many materials are not “all” materials. And the name is “all-purpose glue”. There is usually additional information underneath that says: “…not suitable for styrofoam, PE, PP,…”. I repeat, the name is: “ALL-purpose glue”. I don’t intend to find fault here, these are all top quality adhesive products. But they aren’t all-purpose adhesives.
