Hi Francisco, I'm from Argentina, you're right, you have to put a minimum amount of glue, which would be advisable to put ????
Look I am from Mexico and here we have a special glue for the diffusers, I leave the link of a tutorial where the gluing procedure is performed and the type of glue to use to see if it is essential in your country ... greetings.
