What glues to use for PETG? In analogy to: "What glues for PLA?", what are the best glues to use for PETG?

I mostly print in PETG and have occasional failed prints which I usually reprint. But what if I'd like to repair a print e.g. a split between layers or a part broken off?

Knowing that PETG is more "greasy" than PLA, what typical glues can you use to create a good bond; this question excludes using heat to (re-)bond.
From  forum


  Bison plastic - works great for me, only it's not "quick dry" but it's very strong, not brittle, holds PETG and PLA very strongly. 
  Buy paint stripper that is/contains methylene chloride (dichloromethane). It will solvent weld both PLA and PETG.


Or see  other forum  which recommends Eastman-910 (original brand of cyanoacrylate) or any equivalent, polyurethane glue, or even epoxy.
