I can assure you that the pb300 glue is not a bonding agent. It is more like rubber cement. It adheres 2 materials together via contact. It does not vulcanize the material at all. It dries flexible and "melts" when heated. (not really melts but becomes runny again)
The m.e.k. is used to clean the surface of contamination and can also be used as an activator with pb300. To assist in the hardening phase of the bond.
Well the 465 are pvc, so if all else fails with the nitrile gloves I can fall back on those.
I don't know anything, but I would assume that scuffing with sandpaper and acetone could be in place of the m.e.k.?
