Yea I agree, get someone to hold it, and if you use baking soda it will take off faster, but still leave a white residue ,so take your time ,I have repaired lots of them with super glue,
it will work and leave a small crack but you have no other choice. and you can mix in color ,but you have to be fast.
If you use an accelerator again it will take off fast so make sure you have the parts lined up.
I am surprised yall cant get the good Super Glue I have some dental stuff that is incredibly strong,and comes in a syringe,with a replaceable steel tip,works great every time
