Alright, that replaces part of my worries from the GE applied to the 
Luster consistency :-)
I still think we should be aware that there might be something going on 
with the GE, at the end of the year more test information will be 
available. Some tests were done on the same paper batch. When I read 
that people dedicate an old wide format to apply an extra layer of gloss 
enhancer I think they should be sure that the GE used does not degrade 
the prints on the long run.

With the HP Z gloss enhancer there are other issues like the bronzing 
that is still visible on more gloss papers. The Premier and HM 
protective coats do their job but I like to work with bulk water based 
dispersions. The Premiere Art Eco could be used for papers too I 
understand but I suspect the coating is not that gas tight.
