KEF NT25 tweeter ferrofluid replacement glue question

Hi everyone,

I am going to be undertaking this procedure on my Kef Reference 3.2s and I could do with some reassurance!

I am just wondering what sort of glue I need to use to join the plastic dust cap/surround to the metal magnet back together once I have replaced the fluid?

Is superglue / Gorilla glue too strong?

For reference it's the two pieces shown here: https://audiokarma.org/forums/index...-pictures-and-a-question.709897/post-16063194

Thanks very much!
