The silicone pads in my Dark Magic 2 just fell out one day. Can I glue them back in or what should I do?
No worries, just replace with silicone.
When I fist had a DM2, I had this same problem. The factory silicone wears away overtime. So, You have 2 opitions. You can A: buy replacement pads, but then you have to wait for it to ship. But it is MUCH cleaner then siliconing it. Or you can B: (again) silicone it. This is faster, but a little more messy and takes long for it to dry. But either way, it’s going to cost time and $$$$. This is why I’m not a huge fan of silicone response yoyos. I like the DM hybrid because you don’t have to do anything to it. But that’s just me. 
To get flowable silicone, just go to a hardware store and ask for flowable silicone. I personally use this stuff… http://img2.prosperent.com/images/250x250/www.outdoorpros.com/images/prod/1/Permatex_81915.jpg
