Has anyone ever had to repair a Magnaplanar?

I bought mine about 15 years ago and I didn't know the glue they use is sensitive to UV light. To cut the story short, they rattle because the filament has detached from the frame. There must be a way of reattaching it with a better glue? 

I think a light sensitive glue is a silly idea, that ranks with the British military life jackets that absorb water.
